So, Yog being my favourite faction, i've been looking at what to combine with it. I've tried University, and that worked out ok, and now i've turned to Cthulhu and this is what i've come up with:
3 cursed skull
3 a single glimpse
3 many angled thing
3 servants of glaaki
3 initiation of glaaki
3 glaaki
3 faceless abductor
3 diseased sewer rats
3 mage known as magnus
2 dimensional rift
3 deep one rising
3 deep one assault
3 deep one stowaway
3 dreamlands fanatic
3 nocturnal scavenger
2 pulled under
2 sacrificial offerings
2 ravager from the deep
It's basically a whole slew of 147s and removal, working on the theory that the opponent will struggle to be having any creatures out at all so the kinda mediocre skills of the characters within should be able to take it home. Might need snow graves to combat recursion. Comments/suggestions welcome.
