Only If Thuter is in the battlefield and is
untapped, you may cast this spell.
Thuter's toughness becomes equal to his power,
and he gains Flying, First Strike, and Indestructible for each turn you pay 2 life.
Once, Thuter may tap, and pay {x} to exile your graveyard gaining +X/+X, where X here
equals cards in graveyard
Oh no, he's hot! -Squidward
