Flying When Threzak, the Heinous enters, choose up to three. You lose 3 life for each mode you choose. • Put three +1/+1 counters on Threzak. • Target creature gets -3/-3 until end of turn. • Draw three cards.
Menace {1}{B}{B}: All other creatures get -1/-1 until end of turn. At the beginning of each end step, each opponent loses life equal to the number of creatures that died this turn and you gain that much life.
Devoid Menace {1}{R}, Sacrifice a nonland permanent: Cataclysmic Witness gets +2/+0 until end of turn. If the sacrificed permanent was colorless, Cataclysmic Witness deals 2 damage to any target.
Devoid Crimson Finale deals 1 damage to each player and each creature your opponents control. If a creature dealt damage this way would die this turn, exile it instead.
Whenever you lose life during your turn, choose one that hasn't been chosen — • Discard a card, then draw a card. • Target creature can't block this turn. • Target creature gets +2/+0 until end of turn. • Sacrifice Eldritch Aria. It deals 3 damage to any target.
