By discount, I meant the reference to th 75% win against a deck you tested against (presumably very similar to ours). You discounted our deck and rather put it down to rng. But my point is that as the deck size grows, so does the rng influence... That is all. You were more likely to get an imperfect hand dealt on a deck that relies on quickness to get a lock down.
rng certainly was a big factor, but this isn't a miracle, just lucky. Your deck was slightly reduced in its effectiveness (relative to ours) and we got some great hands.
I still hate your pestal deck. It is really hard to beat. And with your huge vault, I don't think this 30 card loss is going to get rid of pestal.
