Okay, I just recently picked up Goblins for Legacy after having played with it a lot in Vintage. Anyway, what's your plan against Threshold on the draw. Would you just run into Daze or play around it with Lackey and Vial? Would you play a first turn Lackey or a first turn Relic assuming you have another good Goblin in your hand? Would you side in Chalice of the Void against Threshold?
So if EE is used to combat randomness it's probably safe to cut it then. In Holland the people generally just play good decks and the bad players might play random decks but I should have no trouble defeating them anyway.
I truly dislike Thorn of Amethyst, you've got better things to do on turn 2 and my T1 experiences with Thorn of Amethyst were really mediocre. And if it's mediocre there (with all the acceleration and lack of creatures in the format), it should be just bad in Legacy if you can't run it out on turn 1.
