Hisuian Zoroark ex Butterfree is a unique hybrid deck that combines a resilient Stage 2 Grass attacker with a powerful Stage 1 late-game closer. The deck is not designed to rush one huge attacker immediately. Instead, it establishes Butterfree quickly, uses healing and efficient attacks to create favorable exchanges, and allows Hisuian Zoroark ex to become increasingly dangerous as the game progresses. The main early-game engine is Caterpie. Its Quick Growth Ability allows Caterpie to evolve at the end of your opponent’s turn while it is in the Active Spot. This means that when Caterpie survives an opponent’s turn, it can evolve directly into Metapod from your deck before your next turn begins. On your following turn, you can evolve Metapod into Butterfree from your hand and begin attacking immediately. This interaction makes the Butterfree line much faster and more reliable than a normal Stage 2 evolution line. Rather than waiting through multiple turns with a fragile Basic Pokémon, Caterpie can safely advance into Metapod during the opponent’s turn, allowing you to reach Butterfree much sooner. Butterfree is the main board-control attacker. Its attack, Sunny Wind, deals 60 damage for only one Grass Energy and heals 20 damage from Butterfree after attacking. This is extremely efficient. Butterfree can attack early, heal off chip damage over time, and remain active longer than opponents expect. Because Sunny Wind costs only one Energy, you can start applying pressure quickly while continuing to develop Hisuian Zoroark ex on the Bench. Hisuian Zoroark ex serves a different role. Its attack, Spiteful Illusion, deals 80 damage for three Energy, then gains 20 additional damage for every Pokémon in your discard pile. Unlike the Froslass version of Hisuian Zoroark ex, this deck does not use a dedicated discard engine. Instead, Zoroark ex becomes stronger naturally as Caterpie, Metapod, Butterfree, or other Pokémon are knocked out over the course of the match. That makes Hisuian Zoroark ex a strong late-game transition attacker. Early in the game, Butterfree should usually be your preferred Active Pokémon. Once your opponent has taken knockouts and your discard pile has grown, Hisuian Zoroark ex can enter the Active Spot with much higher damage potential. The deck also uses important Grass support cards. Fragrant Forest can add a random Basic Grass Pokémon from your deck to your hand once during each player’s turn. Because Caterpie is the only Basic Grass Pokémon in this list, Fragrant Forest effectively functions as a Caterpie search engine. This makes it much easier to find your evolution starter and begin the Quick Growth sequence. Quick-Grow Extract provides another evolution shortcut. It can evolve one of your Grass Pokémon into a random Pokémon from your deck that evolves from it. In this deck, it is primarily used to accelerate Caterpie into Metapod or to improve the consistency of your Butterfree line. It gives the deck an additional way to establish Stage 2 pressure without relying entirely on drawing every evolution piece naturally. One important detail: Elegant Cape cannot be attached to Butterfree, because Elegant Cape only works on Stage 1 Pokémon. Its best target in this list is Hisuian Zoroark ex, which is a Stage 1 Pokémon. The additional 30 HP makes Zoroark ex much more difficult to knock out and gives it a better chance to survive long enough to deliver a decisive Spiteful Illusion attack. Full Deck Guide Deck Overview Hisuian Zoroark ex Butterfree is a flexible evolution deck with a strong early-game attacker and a powerful scaling finisher. Butterfree is responsible for early pressure, board stability, and damage trading. It only needs one Grass Energy to attack, making it one of the most efficient attackers in the deck. Sunny Wind deals 60 damage and heals 20 damage from Butterfree, allowing it to outlast smaller attackers and recover from gradual chip damage. Hisuian Zoroark ex is the deck’s late-game damage threat. It requires more Energy than Butterfree, but it has a much higher damage ceiling. Every Pokémon in your discard pile adds 20 damage to Spiteful Illusion. As the game develops and your evolution pieces are knocked out, Zoroark ex becomes more dangerous. This creates a natural progression: Caterpie starts the game and accelerates into Metapod. Butterfree becomes the early attacker and trades efficiently. Fragrant Forest helps find more Caterpie when needed. Quick-Grow Extract improves evolution consistency. Hisuian Zoroark ex takes over once your discard pile has enough Pokémon to increase its damage output. The deck rewards patience. Do not treat Hisuian Zoroark ex as your default attacker from turn one. Its damage is much more valuable after your opponent has already been forced to deal with Butterfree. Key Cards Caterpie Caterpie is the most important setup Pokémon in the deck. Its Quick Growth Ability activates at the end of your opponent’s turn when Caterpie is in the Active Spot. It allows Caterpie to evolve into Metapod directly from your deck. This means Caterpie can progress through the first part of its evolution line without requiring you to manually draw Metapod. The ideal sequence is simple: Start Caterpie in the Active Spot. Survive your opponent’s turn. Use Quick Growth to evolve into Metapod. Evolve Metapod into Butterfree from your hand on your next turn. Attach one Grass Energy and begin using Sunny Wind. Caterpie is fragile, so protect it whenever possible. If the opponent can knock it out immediately, you may need to use Poké Ball, Fragrant Forest, or Quick-Grow Extract to find another evolution line quickly. Metapod Metapod is the bridge between Caterpie and Butterfree. Its main job is to exist long enough for you to evolve into Butterfree. Because Caterpie can evolve into Metapod from the deck at the end of your opponent’s turn, Metapod is often much easier to establish than in standard Stage 2 decks. This makes the deck more consistent and reduces the risk of being stuck with an unevolved Caterpie for multiple turns. Metapod can also attack in emergencies, but its main purpose is enabling Butterfree. Butterfree Butterfree is the main early and mid-game attacker. Sunny Wind deals 60 damage for one Grass Energy and heals 20 damage from Butterfree. This makes Butterfree extremely energy-efficient. It can start attacking quickly, maintain pressure, and recover from damage while continuing to attack. The healing effect is particularly strong against decks that rely on smaller repeated attacks. If the opponent cannot deal enough damage in one turn, Butterfree may be able to heal off enough damage to survive multiple exchanges. Butterfree should usually be your preferred Active Pokémon during the early game. Its low Energy requirement allows you to build a separate Hisuian Zoroark ex on the Bench while Butterfree handles the first exchanges. Hisuian Zoroark ex Hisuian Zoroark ex is the deck’s late-game closer. Spiteful Illusion deals 80 damage for three Energy, then gains 20 damage for every Pokémon in your discard pile. Since this deck plays multiple evolution pieces, it naturally develops Pokémon in the discard pile as the game progresses. For example: With one Pokémon in the discard pile, Zoroark ex deals 100 damage. With two Pokémon in the discard pile, it deals 120 damage. With three Pokémon in the discard pile, it deals 140 damage. With four Pokémon in the discard pile, it deals 160 damage. The best time to use Zoroark ex is when its damage reaches an important knockout threshold. Do not rush it into play when it is only dealing modest damage. Butterfree is generally more efficient in the early game, while Zoroark ex becomes much stronger after your opponent has already removed some of your Pokémon. Fragrant Forest Fragrant Forest is a major consistency card in this deck. Once during each player’s turn, that player may put a random Basic Grass Pokémon from their deck into their hand. Because Caterpie is the only Basic Grass Pokémon in this list, Fragrant Forest effectively gives you repeatable access to Caterpie. This makes it easier to replace a knocked-out Caterpie, establish a second Butterfree line, or keep your Bench prepared for future turns. Remember that your opponent can also use Fragrant Forest. The Stadium is strongest when your opponent does not play Basic Grass Pokémon or when your own Caterpie consistency is more valuable than the possible benefit they receive. Quick-Grow Extract Quick-Grow Extract adds another layer of evolution consistency. It lets you choose one of your Grass Pokémon in play and evolve it into a random Pokémon from your deck that evolves from it. In this list, it is mainly used to accelerate Caterpie into Metapod and reduce the time needed to establish Butterfree. Quick-Grow Extract is especially valuable when Caterpie is on your Bench and cannot use Quick Growth from the Active Spot. Instead of waiting for Caterpie to become Active and survive a turn, you can use Quick-Grow Extract to move the evolution line forward immediately. Elegant Cape Elegant Cape should be attached to Hisuian Zoroark ex. It gives the attached Stage 1 Pokémon an additional 30 HP, making Zoroark ex much more difficult to knock out. Since Zoroark ex is a two-point Pokémon and often enters the game during the late stages of a match, the extra HP can be extremely important. Do not attach Elegant Cape to Butterfree. Butterfree is a Stage 2 Pokémon and does not qualify for Elegant Cape’s effect. Guzma and Giovanni Guzma gives the deck a valuable answer to opposing Pokémon Tools. Use it when the opponent relies on defensive tools, HP boosts, damage tools, or utility tools that prevent you from reaching key knockouts. Giovanni increases the damage of attacks used by your Pokémon during that turn. It is most useful when Butterfree or Hisuian Zoroark ex is just short of a knockout threshold. Since this deck often deals fixed damage amounts, a +10 boost can turn a missed knockout into a winning turn.
Your early-game priority is to establish Caterpie and begin the Butterfree evolution line. Try to start with Caterpie in the Active Spot whenever possible. This gives you access to Quick Growth at the end of your opponent’s turn. If Caterpie survives, it can evolve into Metapod directly from the deck, allowing you to evolve into Butterfree on your next turn. Use Fragrant Forest early when you need Caterpie. Since Caterpie is the only Basic Grass Pokémon in the deck, Fragrant Forest reliably finds it. Poké Ball should usually be used to find Caterpie or Hisuian Zorua, depending on which line is missing. In most games, Caterpie is the higher priority because Butterfree is your fastest attacker. Avoid committing too much Energy to Hisuian Zorua during the first turns unless your Butterfree setup is already secure. Butterfree only needs one Grass Energy, so it is usually better to attack with Butterfree while Zoroark ex develops in the background.
During the mid game, Butterfree should be applying consistent pressure with Sunny Wind. Attack for 60 damage, heal 20 damage, and force the opponent to take repeated exchanges into a Pokémon that can recover damage every turn. This is where Butterfree can create a major advantage against decks that lack one-hit knockouts. At the same time, start preparing Hisuian Zoroark ex on the Bench. As your Pokémon are knocked out, Zoroark ex’s damage increases naturally. Keep track of your discard pile and calculate Spiteful Illusion every turn. Use Giovanni when Butterfree is just short of a knockout. Use Guzma when the opponent’s Tool cards are protecting a key Pokémon or changing important damage thresholds.
The late game belongs to Hisuian Zoroark ex. By this point, your discard pile should contain enough Pokémon for Spiteful Illusion to threaten high damage numbers. This is the best time to attach Elegant Cape, bring Zoroark ex Active, and start taking major knockouts. Your ideal late-game scenario is one where Butterfree has already forced the opponent to take awkward exchanges, while Hisuian Zoroark ex now has enough damage to remove their strongest remaining attacker. Be careful with your remaining Pokémon. If you only have one Butterfree or one Zoroark ex left, do not expose it unnecessarily. The deck is strongest when you can force the opponent to answer one attacker while another attacker is waiting on the Bench.
