Yep, you're definitely going to run into these. Particularly as you climb the ranks. In fact, because the player base has shrunk, you're more likely to come up against these expensive decks (as those players would be the last to quit).

This is gonna be a tough deck for most, but note that even at .91 ETH, the win rate is 60%. Not 80%+. My guess is that aggro decks do the best against it. Probably deception with lots of hidden would give it fits.
