I'm going to play my Necrovalley. The only reason I didn't beat Will is because I didn't add counters in my side deck. But I am pretty confident my Necrovalley could take any dude on. Out of DaD, Lightcrap, Perfect Circle, Zombies, GB, the only trouble I would have is with gladiator beast because they attack too much and then beat up my spy and necrovalley field. But a proper side deck should whoop everything.
I was thinking about adding Van'dalygons in my main, but it's too difficult drawing vans and counters at the same time. I tried it in the psp game, and didn't have consistent opportunities to bust it with 3 vans, and 7 counters.
