As I got a lot of "draft" cards is was thinking about building a deck around it.
I already asked google for some help, and this is what I finally came up with:
https://deckbox.org/sets/915604

Anyone any ideas about some major changes here?
The deck is mainly for casual play, most of the times multiplayer.

I just asked a friend of mine and we added some cards, thought about some synergies and ended up with 77 cards...
it only gets worse :)

So a few cards seem out of place here:

- Wickerbough Elder really doesn't work with Master Biomancer as +1/+1 counters and -1/-1 counters actually cancel one another out (as in if a creature has both, they both fall off and cease to be on the creature).

- Wonder really doesn't do much for you.

- Sapphire Drake is good and all, but I'd suggest looking into Kalonian Hydra instead.

- To that end, Glen Elendra Archmage works rather well with Master Biomancer as the persist will interact with the +1/+1 counters to allow it to trigger persist frequently.

- Why 4x Mirrorweave?

- I'd say you definitely want more Master Biomancers.

- I'd also suggest topping the curve with Prime Speaker Zegana.

- Zameck Guildmage can also provide you with added card draw, which is critical in blue/green strategies.

Hopefully some of this helps. Best luck!

You need some means by which to interact with the opponent's side of the board.

I didn't think about the interaction of Wickerbough Elder and Master Biomancer.
Wonder, same as Sapphire Drake is for my evasion. I'm not sure if 4 "giving flying cards" are perhaps a bit much, especially with a good carddraw.
Kalonian Hydra is a funny alternativ to Vorel of the Hull Clade!
Mirrorweave allows me to whipe the board of my opennents or to pump my own creatures.
Prime Speaker Zegana is nice, but doesn't fit 100% to the graft/counter-idea.
For my carddraw I want to use Rhystic Study - my alternativ was Sage of Fables, which interacted perfect with Glen Elendra Archmage.

I thinned out the deck a bit.
What do you think?

- Glen Elendra gets -1/-1 counters, so it won't work with Sage of Fables. You need the biomancers to make that work.

- Rhystic Study is really easy to get around and, as long as the opponent is willing to pay 1 more for their spells, you draw nothing.

- Prime Speaker Zegana will almost always be rather large and being able to draw 4+ cards is pretty solid... even if they remove her, you've gotten the benefit out of her.

- As for the evasion, if you're doing things right, your stuff should be big enough that you don't need evasion. You can go through their stuff.

- Mirrorweave won't transfer counters, although it would be funny to target Kalonian Hydra and attack with 3-4 creatures...

- The list is a bit better, but I think it would be best to focus in more on the key strategy and make the list tighter and more consistent. I think you can pull most of the proliferate stuff in exchange for more card draw and/or removal options.

Glen Elendra is a Wizard, and if Sage of Fables lies, she will get a counter everytime she reapears - like after I sacrificed her.

You got a point about Rhystic Study.

About Zegana - i will make up my mind.

At my casual plays I see several Defenders and Deathtouch, so i thought flying is THE option.
I know that Mirrorweave won't transform counters, but it also makes my opponents creatures 0/0. And yes, Kalonian Hydra is the perfect target. :) :) :)

I already thought about adding more Tezzeret's Gambit, giving my carddraw AND proliferate.
Mind Unbound seems like also like a good card draw. Same for Fathom Mage. Novijen Sages also fits to the graft. Triumph of ferocity should also be possible. Zameck Guildmage supports counters, too.

Difficult.
