Your deck looks *alright*, but you have too many things going on here:
-Otys w/ Grav shield
-Titan w/ Grav pull
-Black holes
-Armajio (?)
-Momentums (?)
-Charger spam
-SoG
So, I would choose one and roll with it. Flying titans w/ Grav pull? Then you can keep the otys, add in 5 more titans and 5 more animates (note that these would be upgraded), and add in 4 more gravity pulls. Remove every other non pillar card and one pillar to make it an even 30 cards. Want to focus on black holes? You could use the chargers, 4 more black holes, the nymph, 1 more titan, and take out all the other cards and use pillars or pillars/otys to fill it back up. A deck focusing on otys with grav shield would work with 6x oty 3x grav shield mark of earth with a few basilisk bloods and then some chargers.
However, I would suggest you at the very least take out the armajio, SoG, and momentums.
