I'm no expert at fractal scarab decks but i'll try...
You look like you have way too much gravity quanta. maybe just change mark to gravity,-1 chimera -9 gravity pendulums, and + 10 aether pillars. you should be able to pull of fractal a lot faster now. Maybe you could switch out 1 or 2 time pillars for precog since scarabs only cost 2
quanta and you want speed.
Try out my suggestions and see if its any better.
That would be a HORRIBLE mistake; Scarabs have to eat sometime, you know.

That said, you do have an awful lot

pendulums. I would trade about 3 for

pillars. Chimera is a great card in tandem with Scarab, especially with swarm effect happening - however, that might be a card to take into account carefully because if it comes in early game, it's a dead card in so many ways. If you find a good time to throw it out as a meatshield, DO IT! Make sure you time it right, because its health is exponential with scarabs.
+Catapults
When your fractal Scarabs really get going, catapults will make this deck a nightmare.
+Momentum
Momentum can let your creatures bypass shields, which can prove helpful in many situations.
+Titan, if you have one.
If you have space for a weapon, might as well use it.

When it comes, +Acceleration.
Easy idea. It'll give you a lot more pure damage, and scarabs will survive, with their high health.
Of course, all this advice is towards your original, which I like better.

Mark means that your fractal begins charging up the moment you start the match, and it's the game-changing card in most of the decks. Without it, your creatures cap at some 3 or 4/6.
