Revolt-
At the end of your turn, if a creature left the battle field this turn choose one:
*Sive deals damage to target creature or player equal to the power+ the toughness of the first creature that left the battlefield.
*draw a card, if it is a creature card, you may revel it, if you do repeat this process, you may only repeat it twice.
* return target instant or sorcery card to your
hand from any graveyard.
