Running Mistcutter requires Nylea on the field.

Sylvan Caryatid > Utopia Tree.

I would take put either mistcutter or simic charm on the sideboard and add Kalonian Hydra. Vorel of the Hull Clade has a cool effect, but in my opinion Prophet of Kruphix is better, gives your deck that extra speed, especially if you can ramp into it early game. I always like to see other B/U/G decks, I've never seen one other than mine where I play.

Anger of the gods. Overload mizzium mortars and other things that don't target.

I think it will make your burn spells hurt much more. Since that is the whole point of him. I mean, shock for four direct damage? Seems good.

Guttersnipe?

Could splash black, drop Vorel and add corpsejack menace instead.

4 Phalanx Leader, 4 Sunbound. Possibly Ordeal of Heliod.

Trostani, Selesnya's Voice? Give all that life gaining goodness?

True enough. Acolyte's reward can be annoying, but doesn't prevent them from dropping a dreadbore or doom blade on your creatures.

Rather than Acolyte's reward how about God's Willing? Giving it protection against a chosen color for a turn for one mana rather than the next X damage. Preventing damage doesn't prevent removal. Personally I've never been a a fan of running more than two of each type of legendary, but that's just me.

I think Strionic Resonator would be good in this deck.

Doubling Season? Ajani Caller of the Pride?

Your only trample is Kalonian Hydra, thoughts on Nylea? Not as a creature, but as a four cost indestructible enchantment that gives all your bombs trample.

Don't get me wrong, Experiment One is beastly if you can constantly hit that evolve. Personally, I'm not a fan of Voice. Depending on who you're playing, Voice won't be around for more than one or two turns, and is dependent on either dying, or having them cast instants. Which would probably be some sort of remove, burn or control card to get rid of Voice, and then they would similarly deal with the token.

That's probably about as good as anything I'd come up with. Maybe one Forced Adaptation rather than Primordial? Or keep Vigor? Hard to say.

I'd say drop some of the basic lands for four Ancient Tombs, Drop the Qumulox for Arcbound Ravager and if you're feeling spendy, make some room for mox opals. Ancient Tombs tap for two colorless at the cost of life and with Arcbound you can swing around any blocker.

Not so much the burn, but things like, oh, you just summoned a huge kalonian hydra.. doom blade. Or Hero's downfall to your master biomancer. Fathom Mage? Spark Jolt. Experiment One? Shock. These are instants so it can be done before you equip it with hexproof. That has generally been my experience anyway.

Garruk, Caller of the wilds is great for any creature based green deck. His plus one is nothing but card draw at that point.

Experiment one is cool, but it doesn't really have a place here. The biggest it's going to get would be 5/5. Loxodon Smiter would be a better pick in my opinion.
