Once during your turn (before your attack), if this Pokémon is in your discard pile, you may flip a coin. If heads, put this Pokémon onto your Bench. Then, you may flip 2 more coins. For each of those coins that are heads, attach a different type of basic Energy card from your discard pile to this Pokémon.
This attack does 30 damage plus 10 more damage for each type of basic Energy card, if any, attached to Ho-oh.
