Slightly tweaked from the deck I took to ECQ Dark Frontier. That list had Xenan Initiation and 2 Scorpion Wasps maindeck over the 2 Permafrosts in this list to not lose to "solitaire decks" like Hooru Fliers and, to a lesser extent, Praxis Pledge (also the reason Cirso is still in here). The Hooru Control matchup felt really close during my ECQ games, though I don't know how this would do vs. that deck now.
Some edits: Derry Cathain didn't end up working out. I still like Cirso for his ability to just slam the door on Praxis, no questions asked (just don't block with him if you smell a Shugo Tactic in hand). Auralian Merchant felt more like a luxury than a necessity after extensive testing. Zuberi has been OK. More variance and a lower statline than Titan offers, but allows your Eclipse Dragon to stay in the air. And it's not like Jennev has no cards to deal with opposing flying units. So, I like him enough to keep him. Trimmed down the merchant/fate package to fit everything in. 3 Xo has been fine (there are lists out there with 0 Xo that are doing fine). Everything else is standard fare.
