Hydreigon
Dark Aura Ability
All Energy attached to this Pokémon is {D} instead of its usual type
Dangerous Sword {D}{D}{D}{D} 60
This attack does 40 damage to 2 of your opponent's Benched Pokémon (Don't apply Weakness and Resistance for Benched Pokémon.)
Haxorus
Dual Chop {C}{C} 50x
Flip 2 coins. This attack does 50 damage times the number of heads.
Giga Impact {C}{C}{C} 120
This Pokémon can't attack during your next turn.
My initial thought was that Haxorus was bad and that Hydreigon could pair with Emboar for a cool spread deck...but then I remembered T-Tar exists and spreads for a lot less energy. Then I thought that Hydreigon could pair with T-Tar but when I thought about it two stages 2 and one that has a {D}{D}{D}{D} attack cost even if it is really only a {C}{C}{C}{C} seems too slow for the format. But let's get some other thoughts in! Do you think Hydreigon can see play?
