Volazzo, Fetish Hunter

Whenever another nontoken creature you control
that's one or more colors dies, create a colorless
Trophy artifact token with "Your devotion to
each color and each combination of colors of the
exiled card is increased by one" and "{3}, Sacrifice
this artifact: Create a token that's a copy of the
exiled card. Activate only if your devotion to its
colors is greater than or equal to its mana value."
As it enters the battlefield, it exiles that card.
