Iden, the Collector

Flying

If a creature an opponent controls would die, if that creature was equipped or enchanted, exile each equipment or enchantment under your control until
Iden, the Collector leaves the battlefield. On each opponents turn, that player may cast an aura or equipment from exile under your control. If they do,
you create {x} treasure tokens where {x} is the spells
mana value that was cast this way.
