Controlled Plummet

Exile a creature card from your hand. At the beginning of your next upkeep, flip X coins and cast it by paying its mana cost reduced by {x}. If you lose more than one of the flips, destroy it. If you lose more than two of them, it deals damage equal to its converted mana cost to you and each creature you control.
