Ban Mimikyu

I even tried making a Gengar ex deck just for fun but it’s just too inconsistent and you can’t set up enough Gengars to do much damage with the ability, and anyway Charizard wallops it because it barely ever attaches energy from hand.

@mthverse Mimikyu (Paldea Evolved 97/193) has a Safeguard Ability that says "Prevent all damage done to this Pokémon by attacks from your opponent’s Pokémon ex and Pokémon V." However, Mimikyu can't protect itself from Pokémon-GX (including Tag Teams), Special Conditions or any other effects of attacks done to it. (Damage isn't an effect.)
