I would dispute the fact that it's a card good enough to be featured in a FG killer. I would much rather have an electrum hourglass in it's spot in a FG killer versus a mindgate.
I'm going to disagree.
As long as your FG deck isn't Aether heavy, I like having 1 Mindgate over another Hourglass.
The Hourglasses have to stop drawing once you get control or if you're down to 10-12 cards. The Mindgates can keep on going and going. It's not required. It's more of a preference thing and I think it works.
So in decks with 4 Hourglasses, I'd put in 3 Hourglasses and 1 Mindgate. In decks with 3 Hourglasses... it depends.
1) But once you get to 10-12 cards, you've basically won. And before that, I'd much rather have an hourglass.
2) Mindgate can only copy half (less than half due to hand advantage) of a FG's deck due to double draw. Hence, it's already only half as powerful.
3) Mindgate is only REALLY strong when you get 3-4 going, sometimes 2. A single mindgate I can't see making a FG easier.
I dont get this Mind Gate vs Hourglass discussion at all. I use Hourglass to speed up drawing cards from my own deck. I use Mind Gate to copy opponents cards. Two different cards that do two different things. Mind Gate cannot do what Hourglass can (unless you face very similar deck to your own, when it is clearly better option to have Mind Gate than Hourglass), and Hourglass will never be able to do things Mind Gate can. So what is with this direct comparisson?
Both generate a single card in your hand.
That's the base for the comparison. You can compare any two similar creature cards. Why not compare any two card-in-hand generator cards?
