I seem to keep getting beaten by rainbow decks built on Supernova / Quantum Pillars...
So after playing about with this deck for a while, I came up with this fun little deck:
Hover over cards for details, click for permalink
6u5 6u5 6u5 6u5 6u7 744 744 744 744 744 744 744 744 744 744 745 745 745 745 74b 74b 74o 74o 752 752 752 752 75m 75m 7n2 7n2 7n2 8pj
Has a nice win % against Silver, seems to work against AI4 - haven't put the stats together yet, so let me know how you get on if you fancy trying it
Upgraded Flying weapons are a must, I end up having to sub in some novas with unupped which makes it slow and clunky. Otyugh keeps down any smaller creatures that come out at first, or antimatter if something nasty pops out. Nymphs are very handy, if you don't have some, 3/4 BH works ok, remember you get a supply of BH from SoF.
Keep smashing towers / shields with SoF, and spam BH once your first Discord gets going. Chargers and flying weapons seem to start doing damage very quickly.
