If you're imprinting lightning helix instead of playing it against goblins you've pretty much lost anyways
someone might've responded to this already but you are 100% wrong. Goblins' draw has to be patently ridiculous to beat Scepter-Helix.

edit: oh, you meant imprinting it on Mox. It would depend on the rest of your hand, but this can be right.

I havn't tested this particular version, but when I played the deck in Extended I didn't really care if someone blew up my Scepter; I just played another one or showed them Exalted Angel or killed everything they played.

Not having tested this, I want to add a land, cut the Pristines for Teferis, cut Impulse, cut Stifle, add a Fact, and add more Counterspells. I might also want to maindeck outs to Needle, but I havn't decided.

Anusien: Did you ever test an eight angel sideboard package? Exalted + Lightning?
