Monstermorph: De-Evolution

Can be used each time your Life Point decrease by 1500. Send a monster (except a Token) on your side of the field to the Graveyard. Then, randomly play a monster that is same Attribute and Type as the monster you sent to the Graveyard, but is 1 Level lower from your Deck (the monster must be able to be Normal Summoned.) This Skill can only be used once per turn.
