Remember you don't NEED to make a singularity for the deck, but you will have to waste a tu if otherwise. Tu enemy creature (one with a cool effect like momentum or something preferably) mutate (the mutate will keep the momentum and the first copy will keep GP so on so forth) then TU spam again. With bravery version your not getting as many turns to stack quanta, so 5 TU's is excessive. Also 3 IM is low as you can use them for PC on enemy creatures too. My own version of your version that was inspired by my deck XD:

Why SoR?: Allows for you to use all your creatures abilities instead of maybe 1 or 2 in the event the deck gets good copies for a 4 turn win.
Why Vamp dagger?: Very cheap, high damage. On top of that, stall power! Boo ya'!
Why fog shield?: Synergizes very well with vamp dagger, also stall power in the event of the copies gone wrong.
Why -1aether tower +1 SN?: Better chances to make a singularity. Lol. Also SN gives quantum to creatures abilities as well as TU. Where your using braveries faster quantum is needed.
With these 4 cards you can expect anything and be more draw reliant. If you purely want stall maybe have silence for 1 bravery or replace sor with black hole. Or both. Have fun and put your own twist on the deck.
