Sacrifice any number of permanents. If five colors were among the sacrificed permanents, each player exiles the top five cards of their library. For each player, you may cast up to two cards they exiled this way without paying their mana costs.

Flying
Cards in graveyards lose all names, card types, and abilities.
Spells and abilities your opponents control can't cause you to sacrifice Manticores.

Flying
Your opponents lose the game if their life total is less than or equal to the total number of cards you own in exile and in your graveyard that have flashback rather than 0 or less.

Flying
