Crobat

Whenever you attach a Grass, Fire, or Psychic basic Energy card from your hand to Crobat, Crobat's type (color) becomes the same as that type of energy until the end of the turn.

Flip a coin. If heads, the Defending Pokémon is now Burned and Poisoned.

Flip 4 coins. This attack does 20 damage times the number of heads.
