@Fetchland debate: The biggest problem I see with running a lot of fetches and few fetch targets is that against decs sporting both wasteland and sinkhole you will be in for a rough ride since they can often completly deny you of a color come lategame. Which will lead to you loosing, but I think it's a risk worth taking.
@Nocco: I'm currently running a list 2 or 3 cards of of yours and I very much agree with the changes you have made. Both Enforcer and Predict are the suckors and Trygon and Spell Snare are incredibly powerful tools in the current metagame. I'd definetly play the O-Ring over EE and I'd try to incorporate at least one needle in te main dec, you'll need it and rarely regret having it.
@SPOD-Crew: Have you guys tested Spell-Snare main? I really feel like it's needed and cutting Predict has never pained me.
