Chrimata Master of Procedes

Whenever you cast a instant or sorcery spell,
create a Treasure token. It's an artifact
with "{t}: Sacrifice this artifact: Add one mana
of any color."
Sacrifice three untapped treasure tokens: Return
target instant or sorcery card from your graveyard
to your hand.
Treasure tokens you control enter the battlefield
tapped.
