First instincts suggestions:
I'm assuming the boycott will pass unanimously.

Water has so many synergies, it's hard to tell which they'll pick. Whatever they pick, they'll probably bring some Congeals and an Permafrost Shield. Use Momentum to bypass the shield, or Adrenaline to make it go by faster. Using them both together is possible, but not as effective.

Discord/Black Hole. They won't go with Aether stall, so I'm betting fractal-something. Mindgate is a possibility too. A lot of Aether cards are high cost, so Discord might work well here.
Indrejue vs.
Korugar
I'm not sure about this one. Should we try a Wings deck again? Or Flying Titans?

I have a feeling they will try

, but don't quote me on that. I doubt they'll run gargoyles, as that'll fall right into Grav shield. Voodoo dolls are also unlikely because of momentum. We don't have many perms, so I'm expecting a quanta denial instead. What's our lowest quanta cost deck?

hrmmm
I don't think they'll try a fractal deck twice in a row against us. Perhaps a mutation deck or a rush. Neurotoxin will work best in case of a rush. I wish we had some good AOE spells cards like Rain of Fire or Plague.

QuantumT (Lieutenant)
Not sure. I think they'll go heavy on the CC, so a firemaster deck here? Don't quote me.

Zeru (Master)
I'm scared to death of antimatter, mutations, or Paradox, so I'd like to go
Memorystick vs.
Lava Golem
Not sure here either. I'm tempted to do Armagios and Flying Titans to outlast any firestall they try.
