Okay I've made decks (see official sticky topic)
Some comments on how to play:
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.
Obviously gravity pull your titans to tank and try to trade gravity pulls to avoid titans dying. DON'T use gravity pulls on your opponent because momentum means it is useless.
xKelevra will have an alright deck. Use momentum on Fire Eaters before Rage Potion to make them uber. Alternatively rage potion could be used for defence to kill his creatures.
PhantomFox: nothing much to say really. Try to use momentum on Otyugh if it is necessary or helps to eat for a few more turns while poisoned. Otherwise momentum on Fire eaters does more damage.
Baily18: Devourer and steal are just there to try to stop them doing whatever they try to counter our otyugh eating their weak creatures. Remember, if they have no creature destruction/control, and you only have 2 otyugh with 1 momentum, you should use momentum on 1 otyugh and then use that to eat the other otyugh to get 5 Hp and be able to eat cockatrice.
It is risky using Chargers here but we're basically stuffed in the long run with lack of Pillars anyway and Chargers need a lot of Pillars....
Smokefree: I know I said aether stall but I'm afraid of Unstable Gas. Pulverizer stops both Pulverizer and Flying Owl's Eye to an extent and Earthquake stops the quanta intensive strategies that Air can employ. Gravity Shield is just a random and stops against Dragons.
