Here's the version I'm currently using:
6qq 6qq 6qq 6qq 6qq 6qq 6qq 6rn 6rn 6rn 6rn 6rn 6u3 6u3 6u3 6u3 6u3 6u3 6u7 6u7 77f 77f 7ai 7dq 7dq 7gp 7gp 7k2 7ng 7q5 7q5 7q8 80h 80h 80j
Reasons behind the changes were as follows:
-1 fractal +1 aether gate: This deck doesn't have many creatures in it to begin with and the ones you do have will often be untargetable. Between this and not having enough quanta or having too many cards in hand to use it effectively, fractal was probably the only card in the original deck that I often found myself not using often. Mindgate makes a good replacement for this that can still give you more creatures to play and adds a bit more flexibility to the deck(or yet another target for your opponent's permanent control to have to take out).
-1 Hourglass +1 Eternity: Being able to draw cards quickly is always nice but especially with a relatively small deck like this, decking out could be an occasional problem. 2 hourglasses seems to be enough and eternity helps greatly with the deckout issue. Of course the low number of creatures in the deck is a problem here again but you can either save one lava destroyer for this or hope to grab one of your opponent's with mindgate. And of course you can always use the eternity earlier in the game to deal with their creatures as well(though that would go against the "no cc" theme of the deck)
-1 FFQ +1 Air Nymph: Got the nymph a couple weeks ago and been looking for a good home for it ever since. This deck already has quintessence in it anyway so the nymph fits nicely in here and gives a good source of burst damage to finish your opponent off(or another option for sneaking in some cc if you don't mind cheating
)
-1 shard +1 Improved Heal: The continuous healing from shards is nice but sometimes, especially early on before you can get your shield out, a stronger burst heal can be useful as well. 5 shards + 2 antimatter still leaves plenty of continuous healing ability. More importantly, Improved Heal gives a much better chance of getting a mastery win rather than falling 1hp short with just miracle.
Overall, the original deck is extremely strong, especially against fg's so it's hard to make anything more than minor improvements on it but so far, I've been happy with these changes.
