Gameplay Video

Early Game

On turn one, prioritise finding Greninja or Greninja ex and getting a basic on the bench so you can evolve next turn. Use Professor's Research or Poké Ball aggressively if your opener is weak. Avoid attaching Water energy to a Pokémon that will never attack.

Mid Game

By the mid game, Greninja should be online with a back-up attacker on the bench. Sequence knockouts so each attack sets up the next. Use Cyrus to drag damaged opposing Pokémon active, and Sabrina to force unfavorable switches.

Late Game

Late game, count remaining prizes and build the exact line that closes the game. If ahead, deny the comeback with Sabrina; if behind, look for a single-turn knockout chain through Greninja.

Common Mistakes

• Benching Greninja before you can protect it, letting the opponent snipe your main attacker.
• Attaching Water energy to a Pokémon that will not attack this game.
• Spending Cyrus or Sabrina too early when they would close a prize two turns later.
• Auto-attacking the active Pokémon instead of sequencing knockouts with Sabrina/Cyrus.
• Burning Professor's Research with a full hand and losing closing-turn resources.

Tips & Tricks

• Mulligan aggressively for Greninja or Greninja ex in the opener.
• Bench every basic you intend to evolve as early as possible — empty benches lose tempo wars.
• Track prize counts carefully; this deck usually wants to chain knockouts in the mid game.
• If you fall behind on board, pivot to a single-prize attacker and rebuild rather than giving up a multi-prize knockout.
