MESSI, THE GOAT

If this cards is played, flip a coin.
For heads- You win the game
For tails- Everyone except for you must put every permanent card in play into exile, including lands and their hands. You get to draw 50 cards, and you can play all of those cards without paying any mana. If a planeswalker or legendary creature was put into exile this way, you win the game. (This effect cannot be negated or countered in any way)
