Detritus Titan

Hexproof, trample, haste
Whenever Detritus Titan attacks, put a +1/+1
counter on it, then its controller chooses one
they haven't chosen before—
• Draw two cards, then discard a card at random.
• Each player sacrifices a commander.
• Target opponent gains control of Detritus
Titan at the beginning of the next end step.
