I like the trigger, too. It's nice. :)
Can someone explain to me why that trigger would be good?
Economy of space? Grokability?I don't see why this needs to cost double black. Not a big deal, but does discard need to be protected so much in limited that this has to be 2bb. If you want it to be saved for the heavy black decks, you could also overcost it as a 4B. But I don't think it needs to be protected.
