Might i suggest a Elspheph or 2 she goes very well with your deck.

Dragonmasteroftheworlds I understand the desire of Elspeth, Sun's Champion - but the 2W can sometimes be hard to get, meaning she becomes a dead-draw too often. Her +1 although good in general, isn't necessary - don't need the attackers, nor the blockers. Her -3 although again, good in the clutch - is a bit TOO good, as it may very well destroy more of my stuff than their's. And the flying is just unnecessary.

Elspeth, Sun's Champion is actually a potent enemy to this deck - that's where the Mistcutter Hydra s and Garruk, Apex Predator /Vraska the Unseen come in. They shut her down nicely.

Ok just thought i might mention it you know. Thank you for explaing how she is not very valid to your deck. Keep building good creative decks loved play testing this 1.

Dragonmasteroftheworlds I totally appreciate the thought - thanks! I'm looking at the new cards, and honestly not sure the best way to go with this moving forward in standard. A couple key cards are phasing out (bye bye Domri Rade )... the Kalonian Hydra is also going - but to be honest, I just threw that in for this list, I play it with 3 Hydra Broodmaster , or another Heroes' Bane would be fine... so no real loss there.

As well Vraska the Unseen will be a very sad loss. I guess Garruk, Apex Predator could just be increased to compensate - but having both was so nice.

Xenagos, the Reveler has potential for even more ramp... but I'm really going to miss Domri Rade hexproof/doublestrike. As noted with Elspeth, Sun's Champion I'm leery about any non-green 2-color card... Maybe just one more each of the Ajani's, 2 Garruk, and an extra Kiora?My concern with that, is the amount of dead-draws in stalled out games...

Just throwing this out there, you need to update your description. A lot of cards in your description and comments are irrelevant to the new standard meta.
