Sacrifice
Spend your own permanents on purpose, because something pays you when they go.
A sacrifice outlet is a card that lets you throw one of your own permanents away whenever you like, for free. On its own that is a terrible deal. Next to cards that trigger on a death, or creatures that come back by themselves, it turns your own board into a resource you can spend again and again.
Not this one?
Leave empty for no limit. Cards you own do not count.
