Forretress

It is encased in a steel shell. Its peering eyes are all that can be seen of its mysterious innards.

Poke-BODY — Iron Shell: Whenever you attach a basic Energy card from your hand to Forretress (excluding effects of attacks), you may flip a coin. If tails, put 2 damage counters on each Pokémon (both yours and your opponent's) (excluding any Forretress).

Explosion (100): Forretress does 40 damage to itself.
