Mutant Evolve/graft (Modern)

1 drops:

Cloudfin Raptor- A good one drop to evolve. A bad draw later in the game, but great to get out early. Has evasion and will ramp up to be something terrifying for the cost of U.

Bioshift - There are a lot of combos with this thing, its main uses being: Removing counters to allow further evolution, moving counters to make a large Ooze with Ooze Flux or to make a stronger Master Biomancer or Prime Speaker Zegana, or taking the tokens off of a creature that's being destroyed.

2 drops:

Shambleshark - Selling point #1: It's a friggin Fish Crab. Also, it's another nice cheap evolver that will also evolve all of my 2 drops and below at least once, and its one toughness makes it easy to evolve itself. It also has Flash for surprise evolutions and fun things.

Gyre Sage - Unfortunately, it's not a mutant or anything fun, but it's a 2 mana evolver that will provide mana. It also will evolve all my 1/2 drops at least once, and 1 power is good for receiving evolutions. I only have 2 because I feel I don't need the ramp that badly.

Zameck Guildmage - A cheaper way to buff up creatures coming in so that they can trigger evolves with his first ability, and a way to remove tokens to facilitate evolution while getting the upside of card draw. 2/2 stats lets him evolve all the weaker evolves at least once.

3 drops:

Elusive Krasis - A nice unblockable evolver, with great stats. 0/4 means that he will be easy to evolve as well as evolving a lot of creatures, even after they’ve already evolved once or twice. He's a good target for dumping tokens onto with bioshift since he can't be blocked and has high toughness for blocking.

Renegade Krasis - The bread and butter. Another evolve creature with the nice secondary effect of triggering another evolution on all of my evolved creatures when it triggers on him. 3/2 can be a bit tricky, as it takes a 3 drop or above to be able to evolve him at least once, but he will evolve Elusive Krasis 3 times and all one-two drops at least once.

Plaxcaster Frogling - An awesome frog. 3/3 will evolve everything at least once, and his secondary effect is essential to protecting your big evolved guys. Graft is also great, as he's made out of +1/+1 counters, he interacts well with a lot of other cards in this deck like Kalonian Hydra, Bioshift, and Zameck Guildmage.

4 drops:

Cytoplast Root-Kin - Another bread and butter guy. Similar to Renegade Krasis in that he will trigger a double evolution in most guys thanks to his secondary ability. He's also a Graft creature, bringing all the same benefits as the Frogling. He can also be a storage area for extra tokens if I don't have a Bioshift or anything else to move/remove tokens. 4/4 is a good power/toughness combination for evolutions.

Master Biomancer - The King. He simply blows away the threshold of this deck. Most creatures can't be evolved beyond 4 or 5 power as there simply are not enough high powered creatures in this deck, so at that point, you'd need to start shuffling counters around to continue evolving. However, Master Biomancer is similar to Zameck Guildmage in that he powers up creatures when they are played from my hand, making evolution easy, and he can power them up indefinitely as long as you can continue moving tokens onto him. He can provide a head start or completely close out a game. He can become even more powerful through the use of Zameck Guildmage, Graft, and Bioshift. Once you get a token on him, you can multiply them through Renegade Krasis, Cytoplast Root-Kin and Kalonian Hydra. His 2/4 stats are acceptable for evolving other creatures as well.

Ooze Flux: Facilitates evolution. The removal of tokens allows creatures to evolve again, and converting the tokens you remove into a creature allows you to evolve your creatures again. It's a +1/+1 engine! As it isn't a tap effect, it can be used at instant speed for surprise evolutions, like with Shambleshark, or for removing tokens from a doomed creature, like Bioshift. It also synergies amazingly well with Master Biomancer, as the Oozes it puts out will be buffed by him.

Triumph of the Hordes: A simple finisher. I have a lot of big creatures, but no evasion. This fixes that.

5 drops and up:

Kalonian Hydra - A definite Win More card. Doubles tokens on everything every time it attacks. It's made up of tokens so it benefits from the same things as the Graft creatures. 4/4 is a nice body for evolutions as well.

Momir Vig, Simic Visionary - A basic Fetcher. His 2/2 stats aren't going to be evolving anything, but 2/3 of the creatures in this deck are both blue and white, allowing him to fetch cards to my hand the majority of the time. Can be used to pull out whatever I need, a basic evolution creature, a Master Biomancer to increase my evolution threshold, Kalonian Hydra to snowball all my creatures, or Zegana for card draw and a guaranteed evolution trigger.

Prime Speaker Zegana - I would say this is another win-more card, as it's pretty useless if I don't have anything on the board, but amazingly powerful if I do. She's guaranteed to evolve all my creatures at least once, and will refill the gas tank with her card draw ability.

Well, there's my deck. Please leave any input or feedback, I'm interested to hear what people think.
