Dear folks, at the moment i'am playing the gate and testing the follow sideboard suggested by hollywood (4 spinning dark, 3 faerie, 3 soul sipkes, 3 dystopia, 2 sword of light and shadow). Just some thoughts: against cemitery, i tried 4 planar voids and i have found that they work very well against dredge and loam, besides the fact that they simple makes tarmogoyfs, reliquaries and lavamancers useless. The problem is that they decrease the power and effectiveness of therapies.
Regarding the matchs against goblins: i think one problem agaisnt this deck is duress. Besides a vial or a werring weird we can do nothing to this deck with duress. Just a thought: considering we have therapies that can catch almost everything, can be good to replace duress with inquisiton of kozilek to reinforce the gate against goblins and elves.
At the moment i play this list:

At least, i love the deck and i feel it is very flexible to any environment.
