I've tweaked it a bit:
and I'm doing ok in Diamond with it:
There's a lot of 1-ofs in it, but that's because some of the legendaries (I'm looking at you, Locke and Zurael) are a bit too memey to want to waste spirit on, and where there are 1 ofs, there are other cards that do the same job so we still get the consistency.
Zurael and Nether Summoning are equivalent: they bring back more Sarlacs. Spell Jammers and Rite of the Undervault likewise. Shadow Sister K & Lady Lock both stall. You could have 3 of either or any mixture of both.
Gloomchaser and Healing Mystic are Filler to get me to 9x2 drop minions.
1. Hilarious when it pulls out a Juggernaut
2. Good with Blood Echoes
3. Often eats a silence, and then can be brought back with Consuming Rebirth
Shadow Dancer / DFC are your win conditions, if they don't concede first.
I'm using DFC instead of Soul Grimoire because
1. I haven't got any Soul Grimoires =)
2. I think it's more likely one of your many many Sarlacs will be in range of the enemy general and not provoked when it comes time to go for the kill.
