Dedenne ex Zeraora Oricorio is one of the more creative Lightning decks currently appearing in the tournament scene. The deck does not rely on a traditional evolution line or a single oversized attacker. Instead, it builds a board full of Pokémon Tools, turns those Tools into damage through Dedenne ex, and uses Zeraora, Oricorio, Elemental Switch, and utility Trainer cards to create flexible turns. The main attacker is Dedenne ex. Its attack, Dede-Circuit, deals 40 damage for each Pokémon Tool attached to one of your Pokémon. Since Pokémon TCG Pocket allows up to four Pokémon in play at once, you can theoretically have four Pokémon Tools attached across your Active Pokémon and Bench. That means Dedenne ex can reach 160 damage when your full board is equipped. This gives the deck a very unusual damage pattern. Dedenne ex can attack for modest damage early, but it becomes much more dangerous as your board develops. With two Tools attached, Dede-Circuit deals 80 damage. With three Tools, it reaches 120 damage. With four Tools, it reaches 160 damage. Because the deck runs Giant Cape, Rocky Helmet, and Small Balloon, your Tools are not only damage modifiers. They also improve your survivability, mobility, and punishment potential. The deck’s second major piece is Zeraora. Zeraora’s Thunderclap Flash Ability allows it to attach a Lightning Energy from the Energy Zone to itself at the end of your first turn. This gives the deck an important early Energy boost and can make Zeraora ready to attack sooner than opponents expect. Zeraora itself can attack with Lightning Claw for 50 damage, but its bigger role is as an early Energy holder and pivot Pokémon. With Elemental Switch, you can move a Lightning Energy from one of your Benched Pokémon to your Active Pokémon. This means Energy placed onto Zeraora through Thunderclap Flash does not always need to stay there. You can later transfer that Energy to Dedenne ex and speed up your main attacker. This creates one of the deck’s strongest tempo lines: Start with Zeraora. Use Thunderclap Flash at the end of your first turn. Place a Lightning Energy onto Zeraora. Bench Dedenne ex. Use Elemental Switch to move Energy from Zeraora to Dedenne ex. Attach Energy manually when needed. Attack with Dedenne ex while your board is equipped with Tools. The third Pokémon in the deck is Oricorio. Oricorio’s Safeguard Ability prevents all damage done to it by attacks from opposing Pokémon ex. This makes it a powerful defensive answer against ex-heavy decks. Oricorio can sit on the Bench as a safety option, or it can become Active when your opponent depends almost entirely on Pokémon ex attackers. Oricorio does not win games through large damage. It wins games by making the opponent’s attacks ineffective. Against decks that cannot damage Oricorio with non-ex Pokémon, they may be forced to retreat, waste resources, or change their entire game plan. This gives you extra time to set up Dedenne ex, attach more Pokémon Tools, and prepare a stronger attack. The deck’s Tool package is the heart of the strategy. Giant Cape gives the attached Pokémon 20 additional HP. This is useful on Dedenne ex because it only has 120 HP and can otherwise be knocked out relatively easily. Giant Cape can push Dedenne ex to 140 HP, forcing some opponents to deal more damage or spend an additional turn attacking. Rocky Helmet punishes opposing attacks. When the Pokémon holding Rocky Helmet is damaged by an opponent’s attack, the attacking Pokémon takes 20 damage. This adds an additional layer of pressure. Your opponent may need to attack Dedenne ex to remove it, but doing so can leave their own attacker weakened and vulnerable to a follow-up knockout. Small Balloon reduces the Retreat Cost of the attached Basic Pokémon by one. This is especially useful on Zeraora, Oricorio, and Dedenne ex because all three are Basic Pokémon. Small Balloon makes it easier to rotate between attackers, promote Oricorio against ex decks, retreat a damaged Dedenne ex, or move Energy around with Elemental Switch before changing your Active Pokémon. Finally, Starting Plains gives all Basic Pokémon in play, including both yours and your opponent’s, 20 additional HP. This Stadium can make your entire board more durable. Dedenne ex becomes harder to remove, Zeraora is less vulnerable during the opening turns, and Oricorio can survive more chip damage before becoming Active. However, the effect is symmetrical, so you should be aware that your opponent’s Basic Pokémon also gain the same HP increase. The deck is best described as a Lightning toolbox strategy. Dedenne ex is your damage engine. Zeraora is your Energy accelerator and pivot. Oricorio is your defensive wall. Your Tools improve damage, HP, retreat costs, and counter-pressure all at the same time. Key Cards Dedenne ex Dedenne ex is the central attacker of the deck. Its Dede-Circuit attack deals 40 damage for each Pokémon Tool attached to one of your Pokémon. The most important part of playing Dedenne ex is planning your Tool attachments. You should not attach every Tool immediately without considering the matchup. Sometimes you need Giant Cape for extra HP. Sometimes Rocky Helmet creates a better exchange. Sometimes Small Balloon is necessary so you can retreat and switch attackers efficiently. Your damage output depends on how many Tools are currently attached to your Pokémon: 1 Tool attached: 40 damage 2 Tools attached: 80 damage 3 Tools attached: 120 damage 4 Tools attached: 160 damage Dedenne ex only has 120 HP, so it should not always be left Active after attacking. Use Small Balloon, Elemental Switch, Oricorio, and Pokémon Center Lady to protect it when possible. Zeraora Zeraora is the early-game Energy engine. Thunderclap Flash gives you an extra Lightning Energy at the end of your first turn, provided Zeraora is in play. This Energy acceleration is valuable because Dedenne ex needs multiple Lightning Energy to attack consistently. Zeraora can hold Energy early, threaten its own 50-damage attack, and later transfer Energy to Dedenne ex through Elemental Switch. Zeraora can also hold a Small Balloon well. Reducing its Retreat Cost gives you more control over the Active Spot and allows you to pivot into Dedenne ex or Oricorio when the situation changes. Oricorio Oricorio is one of the most important matchup cards in the deck. Safeguard prevents all damage done to Oricorio by attacks from opposing Pokémon ex. This makes Oricorio a major problem for ex-focused decks. When the opponent cannot damage Oricorio with their main attackers, they must find a non-ex attacker, use a switching effect, or accept that Oricorio can stall the game while you build your board. Do not automatically place Oricorio into the Active Spot. Against non-ex decks, it may not provide much defensive value. Save it for games where the opponent relies heavily on Pokémon ex and where forcing them to answer Oricorio creates a meaningful tempo advantage. Giant Cape Giant Cape gives the attached Pokémon 20 more HP. Dedenne ex is normally the best target because it is your main attacker and the easiest Pokémon for opponents to target. A Giant Cape on Dedenne ex can move it from 120 HP to 140 HP. Combined with Starting Plains, it can become even more difficult to knock out. This can force the opponent to miss an important damage threshold or commit more resources than they planned. Rocky Helmet Rocky Helmet is both a damage Tool and a defensive Tool. It increases Dedenne ex’s damage because it counts toward Dede-Circuit, while also dealing 20 damage back to the opponent’s attacker when they damage the attached Pokémon. Rocky Helmet is especially good on Dedenne ex when the opponent must attack it to prevent a big follow-up turn. Even if they knock out Dedenne ex, they may leave their own attacker damaged enough to be finished by your second Dedenne ex. Small Balloon Small Balloon reduces the Retreat Cost of the attached Basic Pokémon by one. The deck uses only Basic Pokémon, making Small Balloon extremely flexible. Use Small Balloon to retreat Dedenne ex after it has taken damage, move Zeraora out of the Active Spot after it has provided Energy, or bring Oricorio forward against an opponent that relies on Pokémon ex. Small Balloon is also important because it still counts as a Pokémon Tool for Dedenne ex’s attack. It improves your mobility while increasing your damage ceiling. Elemental Switch Elemental Switch is one of the deck’s best tempo cards. It allows you to move a Lightning Energy from one of your Benched Pokémon to your Active Pokémon. The strongest use is transferring the Energy that Zeraora gained from Thunderclap Flash onto Dedenne ex. This lets you convert Zeraora’s early acceleration into faster Dedenne ex attacks. Elemental Switch can also help you move Energy away from a damaged Benched Pokémon before it is knocked out. This is especially useful when Zeraora has been holding Energy but is close to being removed. Starting Plains Starting Plains gives every Basic Pokémon in play 20 more HP. It improves the durability of all your Pokémon, especially Dedenne ex and Zeraora. However, Starting Plains also helps the opponent’s Basic Pokémon. Use it when the extra HP matters more for your board than theirs. It is especially strong when your opponent relies on damage numbers that are just short of knocking out Dedenne ex.
Your early-game priority is usually to start with Zeraora. Thunderclap Flash gives you a free Lightning Energy at the end of your first turn, making it the best opening Pokémon in many matches. Try to bench at least one Dedenne ex early. You want to begin attaching Pokémon Tools to your board as soon as you understand the matchup. Do not automatically attach every Tool to Dedenne ex. A Small Balloon on Zeraora may be more important if you need to pivot later, while Giant Cape may be more valuable on your first Dedenne ex if the opponent threatens an early knockout. Use Poké Ball to find whichever Pokémon is missing. If you already have Zeraora, search for Dedenne ex. If you already have Dedenne ex but no Zeraora, finding Zeraora is usually the priority because of Thunderclap Flash. Professor’s Research is your main draw card. Use it when you need Pokémon, Tools, or Elemental Switch quickly. Copycat becomes strongest when your opponent has built a large hand.
The mid game is when Dedenne ex begins attacking. Your goal is to have at least two or three Tools attached across your board before committing to a major Dede-Circuit turn. At two Tools, Dedenne ex deals 80 damage. At three Tools, it reaches 120 damage. This is often enough to remove important Basic Pokémon and weakened attackers. At four Tools, it reaches 160 damage, which allows the deck to threaten much larger targets. Use Elemental Switch carefully. Moving Energy from Zeraora to Dedenne ex can create a surprise attack, but do not move Energy too early if Zeraora may still need to attack or retreat. Oricorio becomes important during this stage against ex decks. If the opponent has only Pokémon ex available as attackers, bringing Oricorio Active can force a major interruption. Use this time to add more Tools, heal Dedenne ex, or prepare another attacker.
In the late game, your focus should be on protecting your remaining Dedenne ex while maximizing Tool count. Cyrus is your finishing card. Use it to bring a damaged Benched Pokémon into the Active Spot and take a key knockout. This becomes especially strong after Rocky Helmet has damaged an opposing attacker or after your first Dedenne ex has softened multiple targets. Pokémon Center Lady should be used when healing 30 damage changes knockout math. Healing a Dedenne ex that has Giant Cape attached can force the opponent to spend another attack removing it. Healing Oricorio can also matter if you are using it to wall an ex-focused opponent. Be careful not to overcommit all Tools to a Pokémon that is about to be knocked out. Sometimes spreading Tools across the board is better because it maintains your Dede-Circuit damage even after one Pokémon is removed.
