Exodia, The Obliterator

As an additional cost to cast this spell, sacrifice a non-token creature.

Hexproof, annihilator 2

Exodia's power and toughness are equal to the number of creature cards in all graveyards.

At the beginning of your end step, create an Exodia Piece, a colorless artifact token. Then, if you control at least five Exodia Piece tokens, sacrifice all Exodia Piece tokens: Exodia deals 40 damage to each opponent.
