I like the cultivates but idk what to take out. However the ancient stirrings could be used as a source of ramp, by putting a land into your hand. Plus with the viridian revel and all the artifact destruction you have plenty of card draw.

I'd take out Ajani, 1 Sword, and 1 Argentum Armor for Mana Leaks. I don't see how you can play blue and run no form of control/counter.
