We can't take 12 Darkness Nymphs because we only have one.
Also, either drop parasite or take some death cards. It's pretty useless on its own.
What else.... Take 18 copies of Vampires and Devourers, the most common creatures.
Possibly take more steals and drains for control purposes.
Maybe take some extra pillars, incase someone loses.
I think we should start considering different deck options, as everyone will expect Fractal and we can't run more than 2 of those.
