Upvote for a deck I have been wanting to try but had no drive to, as well as referencing that awesome game. Well done.

Also, Considered Progenitor Mimic?

I have thought about Progenitor Mimic. Probably a sideboard card because I don't really want to add more six drops.

I love Bioshock its sad to say there is no Big Daddy in MTG, +1 man, I've thought about a deck like this with Renegade Krasis and Agoraphobia to boost his abilities on the elves and then use of Zameck Guildmage to draw. I like your deck. I am currently building a mill deck, if you have time comment and/or +1 on it please. Raped by the Creatures of Mill

And you neglected to put in clone effects and Thragtusks because...?

I suppose because the deck operates fine without clone effects and Thragtusks.

It will operate a lot better with clones and Thragtusks. Everything's better with Thragtusks.

needs more digging power and some protection for the combo pieces...

is it a theme deck? cause if it is i'd throw in some Urban Evolution and/or Amass the Components , dunno about the counters you could be running though...

As much as it pains me to promote the card, he could run Spell Rupture if he needs a counter.

I play a casual deck a bit like this, though I lack some Master Biomancers, and its all elves, and my win conditions is usually a big attack, so its not as elegant as this.

A couple of other cards (that probably take it out of standard, but if you ever wanted to play it casual in a different way)

Joraga Warcaller if you can stack counters on him either as he's cast or moving them or adding them later gives all your other elves some insane power bump. 14/14 elvish visionary is no joke.

Vorel of the Hull Clade or Gilder Bairn doubles the counters on one creature, especially with Evolution Vat assuming you can swing the blue mana.

Doubling Season expensive but man, when it ramps it gets serious.

Coiling Oracle is a bit better than visionary, and I usually have the mana to play it.

Wellwisher with all the elves seems excellent.

Cytoplast Manipulator can be used to steal opponents creatures.

Strength of the Tajuru with many elves in play and a joraga in play is game ending for me.

Primordial Hydra with counters, or the ability to double and double again can be tremendous and game ending.

Momir Vig, Simic Visionary fetches other elves for you while playing.

My roommate built the same deck... except he put in Tamiyo instead of Garruk. I have to beat him in 4 or 5 rounds otherwise im f**ked... A very fun deck to play against.

I love the deck because it has a billion ways to win; most of those win conditions taking some creativity to achieve. They never see it coming. :)

upvote from me. Seems like a solid simic deck, and Im a huge fan of a solid Simic, should check out my Simic's Vision. I use similar features, but focus the copying on Progenitor Mimic and Stolen Identity for different reasons, but still a million ways to win, and that's my favorite thing about it. The only thing I wonder about with this deck is the Avacyn's Pilgrim . I see you're running Paraselene and Beck / Call in the sideboard, but I feel with the 4 slots taken by the pilgrim and the slots taken in the side you could find a lot of room for nifty nifty Simic-boosting cards. Just a thought though.Regardless, solid deck and upvote from me.

Pilgrim's in because Llanowar Elves isn't. It needs all the mana dorks it can get and unfortunately that small splash of white is the best I can get until that sliver (haha) of M14 usage before Innistrad rotates out. Those guys may bite the dust for some Elvish Mystics, a flavor-functional reprint of Llanowar Elves, come the time.

Ahhh that totally makes sense. and my mistake not Simic's Vision, but Simic's Vision. I didn't realize someone else had a deck with the same name as that one.

After playtesting I have learned that a major problem with the deck is that it is trying to play 2 strategies at once which is never good. This deck is trying to be both an elf deck and a Biovisionary deck at the same time. Oddly enough, in this deck the stronger strategy is actually the elf ramp one meaning that if you want this deck to be better, you need to take out the flagship card associated with the deck as that's 4 slots you can use to solidify the strategy the deck actually uses to win most of the time. If you need suggestions for what to replace it for, then look no further than the Craterhoof Behemoth in your sideboard.

Additionally, the last thing this deck is basic islands to screw with the mana base. 8 dual lands is more than enough blue necessary to play the 9 or so cards that require it.

I dunno, usually when I play it I simply play it out and whatever strategy appears more prominent is the one that leads me to victory. Like, if I have a bunch of little mana elves and an Archdruid out, I slap Infinite Reflection on it and have a field of huge guys that tap for a bunch of mana, which usually overrun the opponent. If Biovisionary is sitting there, then obviously I win with style points using him. I've played a game where I just got Blasphemous Act ed, had Garruk at six, and six lands. I drew a seventh, played it, played the Memorial, and dropped seven hasty, flying 6/6 wurms out for the win.

The deck has many venues of which it takes to win, and finding those in whatever situation it ends up in is what makes the deck fun. Also, it's just silly to have a six-mana "You win the game" spell when Biovisionary is sitting there with three other guys.

I agree about the lands though. I'll slowly take the islands out to see how it functions without them. Took out two for now. They do kinda muck up the mana base and the dual lands frequently show up anyhow.

But that severely hampers the deck when you could throw them out (along with a Primal Surge) and put in Craterhoof Behemoth as a more reliable win con and more Gyre Sages to ramp up to said Behemoth. It also doesn't help that it's an otherwise vanilla 2/3 that doesn't do anything until you get Infinite Reflection.

If the guy wants to have fun playing the deck then let him play the deck. This deck would be a lot less fun with Thragtusks and Craterhoofs, and a lot less unique. And Thragtusk makes everything better? Tell that to the 50% of people in Standard who don't run him. Might as well tell him to retool his deck to run Boros Reckoner and Voice of Resurgence.

50% of the people in standard don't run it because they don't run green. You don't NEED Thragtusk to win, but if you're playing green and aren't aggro, there's no reason NOT to run it.

Despite that, however, this deck is effectively standard elves meaning it can get away with playing either much cheaper or much more expensive spells (like the Craterhoof). Thragtusk is only necessary if he plans to make this a true Biovisionary deck which, as it stands now, this is not. Right now this is a fairly decent elf deck with the exception that it runs Biovisionary as an "alt wincon" that rarely works.

I've personally played against this deck and rearly does it lose. the alternate win condition is pulled of frequently. It doesn't require as many hops to jump through as you would think

I see how crazy the deck would operate with Thragtusks and if I pulled it onto a more green path with elf aggro, but personally I like winning with Biovisionary. If there's two things you'll learn about my play style, it's that I love elves and unconventional win conditions. This deck is a perfect example of both and I don't want to change it.

However, I am taking the island advice. A starting hand with two islands and a bunch of one drop elves today sealed the deal for me. All islands replaced with forests.

It seems that way until you realize Infinite Reflection doesn't actually change the beast tokens Garruk makes into Biovisionaries (which is why simply saying having 3 other guys out with a reflected Biovisionary is partially erroneous). I tried that once and thought I was going to win until my opponent pointed out that it doesn't work. I still won, but because I replaced a few cards for Craterhoof Behemoths and simply beat the opponent down

I know full well that tokens aren't affected. I conceded a game where I had a beast token, Biovisionary, two other guys, and a Reflection in hand with mana to play it while the opponent had flying lethal damage. I tend to have enough guys out when the time comes, but if not, I Reflect a more savory target like one of their big guys or my Master Biomancer or something. If you're wondering why Garruk is in there if not to make "Biovisionary" tokens, he's also very good card draw and lends to setting up defenders that also get very large when Biomancer's out. They can also evolve a Gyre Sage if need be.

I could tweak the sideboard to allow for me to switch between playstyles if you're so intent on wanting me to go strictly elf aggro. The sideboard could harbor Thragtusks and more Craterhoofs and I could side out the Biovisionaries for them if I want to go that route. Options are always good.

Much to my surprise, you are right in that the Reflection and it isn't a bad card to have in the deck, but right now it looks like you're running Biovisionary for no other reason than you are running Infinite Reflection and it's never a good idea to run cards simply because only 1 card in the deck can take advantage of it.

As for Thragtusks, your deck doesn't actually need them now that I know it's effectively elves. When I first made that comment it was because I thought the deck was suppose to be a real Biovisionary deck that needs Thragtusks to stall the game and to have another card for the numerous clone effects to take advantage of.
