There are too many gravity towers.
I had actually used the exact same idea as a fun deck in trainer (starting with 100 of each quanta), basically animated a Titan, raged it a ton, twinned it a ton, got 300something damage in one turn (had hourglasses to draw more cards).
The only problem with it in the hands of the AI is that the AI isn't going to wait until it has a Titan, animate, and quint and play them all in the same turn. And until that Titan is quinted, it's vulnerable to control every step along the way. Destroy while it's a permanent; mutate, antimatter, rewind, lobotomize while it's a creature. That's probably not a problem seeing as there are 12 Titans and 8 twin universes, but it should be something to think about as once those are controlled, there's no more damage.
On the other hand, the speed at which Titans come out may be too fast. Titans are like Morning Glories, except with momentum instead of immortality. Divine Glory can spam those swords pretty fast sometimes, and it's rare to get a shield without it being exploded. Titans are basically immune to otyughs, which are the main CC in most decks. And since they go through shields, it's hard to stop them. So this may be harder than Divine Glory, which is pretty rough.
Also, there's already a similar FG proposal here (
