Earth is gonna be a real hard task to beat; they have so many new options open and Earth itself is just plain strong. What I don't think they will do is draw the game out; Poison rules long matches, though we can't discount Trident and Purify either; a Purify/Trident/Titanium Shield deck could be deadly. I doubt they will go Gravity/Earth, as they know Otys will likely help us out too much. Frankly, I expect a Shrieker rush though, as they will likely want to end the match quickly. The question is which variant; they used both a quantum denial version, Fractal (didn't think this would work, but ok), and I wouldn't cross out the classic Graboid rush as well.
The question I think is how to counter. One option is a speed poison; the advantages are few towers to lose, but if they use Devourers in force, I could be in trouble. Also, Purifies could hurt even with my Arsenics, of which I don't have unupgraded. I could try Phase Shields in conjunction with Flesh Spiders and Fractal but I'm worried also about quanta and Titanium Shield issues. An Earth/Death deck with Mummies, EQs, and Basilisk's Blood might do alright if I get a good hand. Discord could be deadly if I had any. As it is, I need suggestions desperately please.
Actually, a Death/Darkness deck could be interesting, but I'm sure they'll be packing PAs.
