I'm going to try something a little bit different. Take everything I say with a grain of salt, as it's 90% guessing.
promwarm vs Gravity
We haven't played Gravity yet, but they will no doubt look at our round 1 results and see that we have been rather successful with defensive / stall decks. I'm expecting an Acceleration rush. Adrenaline is actually rather useful against Acceleration used on smaller creatures like Chargers, especially so if we include a Thorn Carapace. An all-out Life rush should be able to outrush Gravity, especially if we throw in a couple Heals and Thorn Carapaces.
Isei vs Earth
We've already showed our hand of Novas to everyone, and they will know that we have like 50 of them. I propose Accelerated Armagios and Chargers. They can take a lot of abuse, simple Chargers don't give a shit about Reverse Time, and they should be able to overtake any Stone Skin / Miracle bullshit.
wizelsnarf vs Aether
Aether used all kinds of control last round. They'll probably expect a heavy CC deck and use immortal boring something blah. Mitosis rush can outrush a deck with expensive Phase Dragons or hands clogged up with useless Quintessences.
Falcon4415 vs Fire
Fire hasn't been very successful with defensive / stall decks. At all. I'm expecting a rush. Fire Shield / Cockatrice to combat that, perhaps?
kitty45 vs Entropy
Entropy's been doing pretty shitty so far using mis-matched heavy CC decks. In my opinion, Entropy is the best element, I'm sort of at a loss. I'd like to see Crusaders just so we can dick around with Discord Saders. Basically, what happened over here (
http://elementscommunity.org/forum/index.php/topic,24171.0.html). Not sure about what they might bring.
wavedash vs Death
They know we have Purify, probably shouldn't use those, not to mention how they actually haven't been using all that much Poison. Death still has Mummies and Recluses, I'm expecting those to come out, maybe with a duo element. Either way, I vote Fractal something.
edunavas vs Time: Fractal Scorpions sounds good.
PlayerOa vs Water
We predicted either heavy CC or a rush last round, Isei was able to pull through. Team Water will either expect the same type of CC-resistant rush or a stall. Steam Machines with Rage Potions probably beats any sort of defensive rush we have, and Ice Bolt sudden kill beats our stalls. Mitosis Frogs with 2-3 Jade Shields takes care of both threats.
