Mad Party

The Mad Party deck focuses on using either Bunnelby or Polteageist's Mad Party attack, which does 20 damage times the number of Pokemon in your discard pile with the Mad Party attack. Polteageist's Tea Break Ability allows you to discard a Pokemon with the Mad Party attack from your hand and draw 2 cards. Galarian Meowth's Evolution Roar Ability also allows you to discard 2 cards from your hand and search for its evolution card. There is no reason to run the Galarian Perrserker in this deck but

The Mad Party deck focuses on using either Bunnelby or Polteageist's Mad Party attack, which does 20 damage times the number of Pokemon in your discard pile with the Mad Party attack. Polteageist's Tea Break Ability allows you to discard a Pokemon with the Mad Party attack from your hand and draw 2 cards. Galarian Meowth's Evolution Roar Ability also allows you to discard 2 cards from your hand and search for its evolution card. There is no reason to run the Galarian Perrserker in this deck but you can still use the Ability to discard cards like Mad Party Pokemon. This deck also has Galarian Moltres V as another attacker, which is a great attacker against decks like Mew VMAX and Dragapult VMAX. Galarian Moltres V's Direflame Wings Ability allows you to attach a Darkness Energy card from the discard pile to the Galarian Moltres V. There is 2 Energy Switch in this decklist so that we can move the Darkness Energy cards from the Galarian Moltres V to a Mad Party attacker in case we run out of Twin Energy. The main strategy of this deck is to go first, Bench 2 or 3 Sinistea, and try to discard some Mad Party Pokemon. On turn 2, then you evolve your Sinisteas to Polteageists, use its Abilities to discard more Mad Party Pokemon and then attack with Bunnelby or Polteageist. Later in the game if you need to, use Galarian Moltres V's Abilities and attack. I hope you enjoy this decklist!
