Return all artifact cards from your graveyard to the battlefield. They gain haste until end of turn.

If you would gain life, you gain twice that much life instead. If you would draw a card except the first one you draw in each of your draw steps, draw two cards instead.

Whenever you gain life, you may pay 2. If you do, create a 4/4 green Fungus Beast creature token with trample.

T: Draw two cards. Target opponent gains control of this creature. Activate only during your turn.

Whenever you gain life, you may pay X, where X is less than or equal to the amount of life you gained. If you do, draw X cards.

Flying Will of the council — When this creature enters, starting with you, each player votes for grace or condemnation. If grace gets more votes, each player returns each creature card from their graveyard to the battlefield. If condemnation gets more votes or the vote is tied, destroy all creatures other than this creature.

For each permanent type, return up to one card of that type from your graveyard to the battlefield. You lose 3 life for each card returned this way. Exile Revival Experiment.
