I would try and consolidate your creatures you have a lot of 2 and 1, you should try and get more 4 of the best and 3 of the less so good then the occasional 2 of if you need to fill in something.
Also 4x farseek, and a couple more lands.

Yeah, I got caught up in all the good cards so I wanted them all in there lol. I do need more voices, but my mana can't handle too many of my game changer cards. And I would LOVE 4x Farseek if I had it, that's my only one! :(

i think im the only person who uses this combo, but cackling counterpart is amazing in tokens

All it's missing is Prime Speaker Zegana .

Your mana curve is a pretty stacked on 4. You are probably going to be hitting 4 drops on turn 5 or 6. I would suggest throwing in some 3 drops instead of some of the four drops. Loxodon Smiter might be a good idea.

Oooooh I didn't think about her! Can't wait to try that out!

I do like Loxodon Smiter once I get some that will be a definite addition! :D

Biovisionary is a deck in of himself and running less then 4 of him and relying on any copying is hopeful at best. especially with as little ramp you have currently. Staff of Nin and Index don't fit, though the card draw is a decent place holder.

With those slots you'll want either more populate or some good three drops. Loxodon Smiter , Centaur Healer , Champion of Lambholt , Crusader of Odric for just a few ideas. Beck along with Call is right up your alley too.

Might also want to consider dropping 2 of the charms to help level out your mana curve.

Wow, that was detailed, but made a ton of sense. I have Biovisionary in there as a failsafe in case I couldn't deal the damage to win. He's gotten me about 40% of the wins with this deck

I won 2-1 against this with my brutalclops deck, this deck is kind of slow and if its intended for long game, needs cards like dissipate, syncopate, maybe some hand fuel, like think twice and divination.

I like the deck, but like most people here, I think it needs some consolidating. Is vitu-ghazi guidmage working for you? I honestly feels like its hopeless with how expensive its abilities are. Emmara tandris isn't very good unless as a commander in EDH so i'd consider dropping her. index or staff of nin might be more useful as azorius charms or shinx's revelation. +1 for mimics though. God, I love that card...

I have a similar deck (no biovisionaries though) if you'd like to check it out.

Maybe Geist of Saint Traft instead of Centaur Healer? You can catch his angel in a populate.

Yea geists is awesome with trostani, populate, parrallel lives, and master biomancer. That is a great idea.

Geist of Saint Traft is a good idea, however its expensive and i don't have one yet. I'll try and get ahold of one. then i can replace Scion of Vitu-Ghazi since i only had him for the flyers.

If you can get a Progenitor Mimic out copying a Scion of Vitu-Ghazi when he creates a copy of Scion you get infinite creatures :P

Scion of Vitu-Ghazi has to be played from hand in order to get the populate. I wish it were that way though! That would be OP!

Oh, haha! Thanks for pointing that out!
