Vulkid, Child of the Cosmos

Deathtouch, Hexproof

At the beginning of each upkeep, exile the top card
of each player's library. You may cast cards exiled this way and spend mana as though it were mana of any color to cast them.

Sacrifice another creature or artifact: Destroy target creature or planeswalker. If a permanent destroyed this way would be put into a graveyard this turn, exile it instead.

Born of starfire and chaos, his cries echo through the void, demanding sacrifice.
