I'm seeing Surge Mares in the core deck now, especially in Bo1. Really good against mono red and the other meta decks you mentioned.
If you're doing Bo1, maindecking Surge Mares makes total sense, IMO. It's far too useful against way too many of the decks of the meta, and even when it's not particularly useful, it's not all that detrimental, either.
The most tilted I've seen someone at a Magic table was against an UB Psychatog. Tog was the pinnacle of the permission control archetype. It was ridiculously oppressive.
Dude was running this RG deck that had Kavus and Mongrels in it. Second game, after he had his second or third Kavu countered in a row, dude just got up, threw his cards into his backpack and left without saying a single word.
