Alright, let me think.
Opponents: Earth, Time X2, Fire X2, Air, Water, Entropy, Light
Primary Available decks:
1) Adrenaline Mercs
2) Discord/Black Hole X2
3) Poison/Deathstalkers
4) Neurotoxin
5) Firemasters
6) Flying Titans
7) Devourers/Black Hole
8) Armored Otyughs
9) Blessed Otyughs
10) Aether stall
I'd take Firemasters against Air, to counter their good perms.
I would NOT take any scorpion against time, or buff based creatures against Time because of Rewind
Something sufficiently low quanta against Earth. Perhaps one of the Discords?
Some form of quanta denial against Fire. The Earthquake/Holes deck posted looks good.
Water is generic enough to take anything
Entropy is hard enough, so I'm not sure here. Discord/BH shut me down hard last round.
Light will require either a really good stall, or our best rush. Adren Mercs perhaps?
