Will, Being of Chaos

At the beginning of each player's upkeep, flip a
coin. If the result is heads, that player sacrifices a creature and draws cards equal to the sacrificed creature's power; if the result is tails, that player discards a card and returns a creature with
converted mana cost less than the converted
mana cost of the discarded card to their hand
Whenever an opponent moves a card from
anywhere to their hand, they lose one life and
discard a card
