In Time Rainbow decks, I try to have ~30% towers. But since you have pillars, you might need to add 1 more. Purify seems a lot more situational than another Empathic Bond, but it definitely is handy against a couple gods. Still, I would really consider taking it out and putting in another bond. Personally, I like Aflatoxin+Bonds+Druid. The AI really can't do much to stop it. And it spreads much faster than even a Boneyard+FFQ together. Plus, an upgraded Aflatoxin only costs 1 more than an upgraded Boneyard. If you don't have a Druid out (mutated Cells become Cells again after the mutated creature dies), you can always Quint 1 Cell to make sure you can refill your board after a AoE spell like Firestorm/Plague.
So I'd make something like this personally:
