Partner with Joseph Joestar
Prowess, Vigilance
Whenever you cast a noncreature spell, add {u}
Whenever you cast your 5th spell in a turn, the next spell you cast gains buyback.
Whenever you cast your 10th spell in a turn, creatures you control get +X/+X until end of turn, where X is the number of spells you've cast this turn.
Whenever Caesar dies, at the beginning of your next upkeep, add {u}{u}{w}{w} and create Zeppeli's Headband.
