Strange Anger and Greed

Whenever a creature dies, put a Greed token
onto Strange Anger and Greed.
Any time a player plays a Artifact or Land,
you can use a Greed token.
If you do, exile the card before resolving
unless its owner puts 2 -1/-1 on creatures
under their control.
If we don't sell more, we're going to be in trouble.
