I'd say cut black and just go Bant. Just Sylvan Caryatid and Courser of Kruphix for creatures. I'd also put in an extra Kiora, the Crashing Wave and 2~3 Nissa, Worldwaker . Divination and Banishing Light couldn't hurt either.

making this deck in the spirit of a sealed KTK 5 color control I ran over the weekend. It succeeded in not always losing, and pissing people off. This is my attempt to bring that to standard. Nissa will be a no go, because it's not in the spirit of the deck, good card though it is.

Kiora is a good call. Weave fate instead of div, for instant effect. Banishing light is a great call,courser too ... thanks for the comment.
