As a pure rush, unupped gravity isn't a very good choice. But with adding a bit flavour of gravity to your mix, this will get probably better.
With your quanta balance now, I would first try -1 pendulum, -1 Acceleration, +2 Gravity Pull for CC.
Then, depending on how you like it, switch a graviton mercenary and a Saphire Charger for two Gravity Dragons, or go for more CC with additional Gravity Pulls by switching another Acceleration out.
Of course, if you have/get a titan, switch one gravity creature (either saphire charger or mercenary) right now.
Edit: You switched the graviton mercenaries for Armagios now...?
