I was looking for something a bit faster because I dislike all the "sit behind Dimensional Shield and stall" type of decks. My main objective was to build a shutdown deck using this but it didn't work all that well.
I think the problem there is that mindgate isn't really meant to be used in a fast deck, but rather in one that is able to stall long enough to set things up first. There are a few reasons for this:
1. You are not only trying to play your own deck, but also your opponent's deck as well
2. Since you (usually) don't know what deck you'll be facing, you need to be prepared to cast anything which means relying fairly heavily on quantum towers(while you COULD simply hope to take enough of your opponent's towers/pillars to power their spells, this would make things even slower and risk missing their towers altogether if you're not able to use mindgate every turn due to needing to cast something else instead like phase shields). On the other hand using quantum towers means you may have to wait a few extra turns to get enough aether to even cast the mindgate in the first place.
3. Ideally, you are not just playing one copy of their spells, but several(at least of the more useful ones)
All of this means in order to be fully effective, mindgates need a huge supply of quanta which in turn requires a decent amount of time to set up first and thus favors a deck which is able to stall at least long enough to achieve this.

http://elementscommunity.org/forum/index.php/topic,11275.0.html) is a deck I made which, while not very effective against fg's, has had very good success in pvp2 so far for me. It has virtually no offense of its own but is able to stall long enough to take control of the opponent's deck and it against them several times over in most cases.
