Whenever you attach a Water, Lightning, or Psychic basic Energy card from your hand to Kingdra, Kingdra's type (color) becomes the same as that Energy card type until the end of the turn.
Kingdra does 10 damage to itself. (Don't apply Weakness or Resistance when Kingdra damages itself with this attack.)
Flip 2 coins. For each tails, discard 1 Energy card attached to Kingdra.
