Liova , Black Mage

Whenever you cast a noncreature spell, you
may have Liova deal 3 damage to, and place a
Nuke counter on target player.
When a player has 20 or more nuke counters,
exile their graveyard, hand, and all permanents
they control. Their life total becomes 1.
"There's no fun in just fire.
Only when it causes chaos."
