I am very tempted to + Karma you just for making a deck with Massive Dragons in it. And for surviving that ridiculous colour scheme.
On a more serious side, I fail to see the use of the Quint. A quinted Gravity pulled creature still gets attacked, right?
So a gravity pull would work better, since it would remove the Gravity pull from the chimera (as long as your opponent isn't about to kill you)
Your pillar useage is 7 and 8. Trying it out with pendulums could reduce bad draws, but you might not get enough gravity. You'd have to look into that.
But it looks good. I'd like to try this in PVP (Need 5 more Massive Dragons).
And welcome to the Forums!
