Gave it a good testing again. Reached the same conclusion. While the deck can highroll, it does not do so often enough or fast enough. Xor on curve is meaningless if you have no board, and have not been removing your opponents board. Cass variant has zero tempo and Xor alone, even when followed by Dancer is often not enough.
If you open with sarlac/gor and they don’t get dispelled and you can either get the BBs engine or the Darkfire engine and can then follow up with dancer its pretty decent…But I was still loosing games with Xor on five mana followed by dancer. And when you don’t open with gor/sarlac or they get answered immediately you roll over and die and have no back up plan. And even when things go perfectly its still far from a for sure win.
Maybe I am missing something, but negative tempo decks that rarely go off before six mana, and still take some time to take off after that point, and rely on so many moving parts without answers just does not feel good at all. I just do not see were you, jay, or moggin are coming from.
I tried it with every realistic combination of the mainboard and sideboard. It just feels like a bad gimmick without maevs tempo tools. Gave it a good 20 games trading out consuming/Mentor and various numbers of desolator for the various sideboard options.
Did Moggin really hit S#1 with this? I don’t know what am I missing, but husks are an absolute must to feel competitive, without them you are left with a fun gimmick that can sometimes work out.
