Elden Beast

•Whenever a non-token creature you control dies, you may exile it. If you do, create a 2/2 black and white Great Rune artifact creature token with flying. You can only create up to three Great Rune tokens this way per turn.

•Whenever you gain life, return a creature exiled with Elden Beast to the battlefield under your control.

•At the beginning of your end step, if you control 7 or more Great Runes, you win the game.
