Im the only one in my area who plays an ETB type of deck and mine is also bant, i use rafiq though, hes just a support piece though. My early game consists of ETB bounce cratures and mystic snake for counter. Stonecloaker and Venser are my two main "save" a creature ETB options. Your build seems more aggro than mine though. Im usually a controller until i can drop Avacyn, then rafiq comes out and she swings for 18 flying. I win about 90 percent of the time. Oh yeah you should really consider deadeye navigator and cloudstone curio if you haven't done so yet. Creatures like body double and Soul of the Harvest are fun too. well hope i helped a little, good luck.
I noticed in your list you play stalking vengeance, i play this in my kresh deck as well, but i combo it with nantuko husk, and symbiotic wurm or mitotic slime. That three card combo can kill two players while thier both at 40 life. I also like playing repercussion with chain reaction or blasphemous act if kresh feels a little suicidal. I hope any of these cards help, and good luck.
Just a few things i find helpful:
Creatures:
Brawn, Gaea's Revenge, Duplicant, Gamekeeper, Oracle of Mul Daya, Seedguide Ash, Loaming Shaman.
Artifacts and spells:
Vedalken Orrery, Altar of Dementia, Hurricane, Howl of the Night Pack, Far Wanderings, and Early Harvest.
I also play Guantlets for another mana ramp.
Most of the time it's ramp early Genesis Wave for like 50 and Altar of Dementia for the win. I hope and of these cards help you and manage to make it into your deck, good luck.
Most of the red blue green colored decks from where I am from involve riku, so its refeshing to see an ETB deck using those colors. Being my areas main ETB player i personally use bant colors for my ETB deck, cascading into ETB creatures is quite nice, red seems to have most of the more useful cascading cards thus far. As for useful cards that might help out check out anything and everything that has a cloning effect in blue, clone effects seem to be huge, hmmm cloudstone curio is really nice. I personally think that solemn simulacrum should be in every deck. Body Double, green suns zenith, or maybe chord of calling. Mulldrifter for some card draw, Venser, shaper savant is amazing. As a small note maybe a survival of the fittest and/or birthing pod, although i do realize that the pod may not be ideal for cascade.
Hope any of these cards help, good luck.
