Who Goes There?

Complete fucking chaos at a discount rate. Pop Agatha in here somewhere and you will never be able to unsee the janky horrors which will unfold before your very eyes. Mr. Negative + Mobius + Cage? Card quality goes through the roof. Pop pixie on top of that and you can wind up with some crazy stuff. Crystal and Magik and Warlock for both consistency and card advantage. Blink/Jubilee/Lockjaw could be added too, but where? Venom might be useful for clearing up space as well.

Sersi operates on lower-case 'c' cost, so not actually good here.
