This deck was made for the Paldea Evolved Format so some cards in the deck were used as placeholders.
Forretress (Flash Fire) -> Forretress ex (Paldea Evolved)
Marnie (Sword and Shield) -> Iono (Paldea Evolved)
Squakabilly (Scarlet and Violet) -> Squakabilly ex (Paldea Evolved)
The focus is around using forretress ex's ability to accelerate 10 energy to exxecutor in 1 turn then use Iono to bring them to a two card hand and use collonge if they get manaphy into play.
