I don't mean to sound rude, but this deck makes no sense to me at all whatsoever. Why is it blue and green just for Master Biomancer , when there are no +1/+1 counters in this deck? It could more simply just be a mono-blue devotion deck with a mana base of just islands and some Nykthos, Shrine to Nyx . Also, a replacement for Simic Charm in terms of protection (I'm assuming the Simic Charm s are used mostly for Hexproof) is Mizzium Skin which is the same thing, and all of your guys get +0/+1, too. If you're using Simic Charm for it's other effects, I just don't think it's worth splasing green for.

Well if Master Biomancer is out anything that enters the field gets 2 +1/+1 counters. Play a second one, it gets 2 and anything that enters after that gets 6. Also if he casts Master of Waves, and drops the elementals, they will be pumped, and can survive if Master of Waves is destroyed. Or with Simic Charm, say an opponent were tapped out, he could Simic Charm Master Biomancer and whatever he casts next gets 5 +1/+1 counters. At least that's just the benefits I see from having the splash of green. But hey, I'm a bit bias towards green :P.

I REALLY like the deck. My only question is how do you deal with board wipes (Looking mainly at Supreme Verdict). In my play-testing with this deck I get AWESOME board presence on turn 5/6. It'd be well within the realm of possibility for our UW friends to wipe us at this point, and it's VERY hard to come back when you devote yourself to the board so heavily. I'm afraid I don't have any good suggestions. The only good 'counter' to verdict is Golgari Charm in GB that isn't really feasible to add in. What are your thoughts?

I'd put in 4x Breeding Pool and cut 4 islands. Also maybe consider Plasm Capture Side-board or even main. I built this deck card for card. I put in the breeding pools in and its great. Ill put in the Plasm Capture and see if it works too.

Bioshift back on to Master Biomancer could wreck before a MoW.

Do you think this deck could hold its own in modern?

I absolutely smashed a guy at FNM using this deck. Not saying the deck is bad at all it is really good and alot better than the one I was use. But people should really stop just looking for the best deck online and buying it, where's the fun in that? Especially if they dont know how to use it

ive test your advanced mutology against my Dauthi Shadow deck and it failed miserably....

What do you think of adding some cards from Khans of Tarkir an Fate Reforged. The Fetchlands The Green/Blue gain 1 life land Yasova Dragonclaw The Seiges and many others
