Ultra Greed

Triggered abilities must be activated when able.
Spells with optional costs can't be cast without
paying for those.
Costs with {x} can't be equal to 0 or 1.
Cost reductions don't apply.
When Ultra Greed enters the battlefield exile
target players graveyard. Create a Gold artifact
token with "{t}: Sacrifice this, add 1 mana of
any color." for each creature exiled this way.
