Just some ideas
We really have to use our other cards so I think Smokefree should go with Aether stall.
jmdt to go with flying titans with the first game as a sort of tester where you play normally. If he goes PU then you won't fly your titan in the 2nd game onwards. If he goes reverse time then take some care with flying titans as well. Fly them when you are going to win.
The deck posted earlier had 11 gravity pillars but we don't need that many. We only need 8. So we can add 1 Flying weapon, 1 Fog Shield and 1 Gravity Pull.
I think xdude will win unfortunately with either earthquakes, fire or flying morning star and pegasus. So I would consider throwing the match. They know we have dimensional shields so he'll probably try to counter it with earthquakes or fire with deflagration.
PhantomFox should go with Otyugh + titans + freeze + purify and novas with chaos seed, poison and lightning, momentum, reverse time. With Gravity mark to save on gravity pillars. This would need only 5 Gravity pillars.
That leaves chargers and otyugh to Baily18 to get past thorn carapace and also eat his creatures up. If they use quintessence then we can't really do anything about it. I think they'll try to counter Aether stall anyway so it should be alright.
