Thanks for the insight, everyone! I was looking at making a mono Shub deck. Is there a link to any deck like this anyone has already made?
I would put up my Shub and Mi-Go decks as examples for you, but as our group plays with both CCG and LCG cards, I don't think they would be much help. Still, after reading dboeren's post in your other thread about Dark Young being his favorite Shub subtype, I got to thinkin'...
I like Mi-Go, and I like Dark Young. They're two great flavors that, well, you know. So what about something that tastes like this?
x2 •Shub-Niggurath, Dark Mistress of the Woods
x3 Hungry Dark Young
x3 The Mother's Hand
x3 Ancient Guardian
x3 Mi-Go Caretaker
x3 Ageless Mi-Go
x3 Mi-Go Scout
x3 Mi-Go Surgeon
x3 Priestess of Bubastis
x3 Grasping Chthonian
x3 Telepathic Chthonian
x3 Under the Porch
x3 Burrowing Beneath
x3 Mi-Go Skull
x3 Mi-Go Scalpel
x2 Altar of the Blessed
x2 Summoning Circle
The card ratio in this deck goes against my general design philosophy, but with Shub I find it's fun to run a boat-load of characters. Even if they die like flies, there's always more where that came from.
The deck's general premise is to make either Shub-Niggurath or Y'Golonac a Mi-Go character with tons of skill, arcane, and of course investigation (thanks to the Mi-Go Skull, Mi-Go Scout, and Mi-Go Scalpel). Then, as they're invulnerable, send them in to a story and slowly grind away to success.
You've got your Ageless Mi-Go to protect against lots of wounding, and if you're facing an opponent that forces you to sacrifice a bunch of characters just make sure they're Dark Young and then bring them back as fodder for the next turn with Shub. Use the Grasping Chthonian + Telepathic Chthonian + Under the Porch to nullify your opponent's support cards, and do some sacrificing of your own.
Finally, bring out the Mi-Go Surgeons and exhaust your Summoning Circle to grab whatever character you need (namely your Ancient Ones).
P.S. Instead of the Summoning Circle (if you feel having it and Under the Porch to be repetitive), you could go with either x2 Open Grave, Specimen Room, or Mi-Go Laboratory.
