Magik, Ruler of Limbo

Eldritch Gate — At the beginning of your upkeep, exile the top two cards of your library. You may
play those cards this turn. If you cast a spell this
way, you lose life equal to its mana value.

Soulbound Sword — {2}{b/r}, Sacrifice a creature: Magik gains +X/+0 and menace until end of turn, where X is the sacrificed creature's power.

Whenever a creature dies, each opponent loses 2 life, and you gain 2 life.
