I've had quite nice experiences with this deck. Surely it does lose more often than you'd want due to bad draws, Rewinds and Discord. Still, I built the deck last Thursday and without too much playing, I finally got to plat league. I was level 57 and now I'm way over 60, which means over 30k score gained. Certainly a deck worth building if you're looking for score grinding. I think I've gotten 6-7 special spins now, so it's not that bad in getting spins either.
Gets a little easier to play with some experience; eg. AI will use Attack increasing creature skills even when you're under SoSac. Faced Archangel/Fire Nymph deck and the AI merrily buffed the Angels over 50 attack while I was covered with SoSacs.
Mitosis is another fine example which might allow to use SoSac even when you're under the 20 attack limit.
Thanks to Calindu for suggesting this one over SPlat.
