Flying, trample

At the beginning of your upkeep, sacrifice a Human. If you can't, tap Archdemon of Greed and it deals 9 damage to you.

As an additional cost to cast this spell, you may sacrifice any number of Spirits.

Target player loses 2 life plus 2 life for each Spirit sacrificed this way. You gain that much life.

When Greed's Gambit enters the battlefield, you draw three cards, gain 6 life, and create three 2/1 black Bat creature tokens with flying.

At the beginning of your end step, you discard a card, lose 2 life, and sacrifice a creature.

When Greed's Gambit leaves the battlefield, you discard three cards, lose 6 life, and sacrifice three creatures.

You lose 2 life and draw two cards, then clash with an opponent. If you win, repeat this process. (Each clashing player reveals the top card of their library, then puts that card on the top or bottom. A player wins if their card had a higher mana value.)

Put target creature card from a graveyard onto the battlefield under your control. That creature deals damage equal to its power to each other creature.

As an additional cost to cast this spell, sacrifice a creature that dealt damage this turn.

Draw three cards. Each opponent loses 3 life and you gain 3 life.
