My thought on Chapel/Mine was, "have my good card" sometimes, I'm lean enough to recover. It's rare I'd give up a gold (which is what I'd value most) and once Chapel was no longer useful, spam the Chapel to him. Let me dial up a simulator...I'm sure you guys are right...but I think my hate for the card is making me think that density can survive, when clearly every article I've read and all the comments here are saying I have to get on the Masquerade wagon or die.
EDIT - Basic simulations bear out that BM+Masquerade will defeat BM+Mine, BM+Chapel easily. I can tune BM+Chapel to about a 30% victory, but no higher. You spend too much energy trashing the junk, or drawing junk, while Masquerade slowly tunes itself to optimal strength.
