I mentioned this possibility before in my article on my Crypt Rats deck. There I was thinking that this deck might be a little too much EDH and not enough Pauper. However, despite this, [scryfall]Species Gorger[/scryfall] definitely has an appeal to me as a commander. Its just a matter of finding enough creatures with ETB and LTB abilities at common.
For obvious power level and NWO reasons, there aren’t that many good ETB effects at common. Some, but not many. In fact, our deck is pretty much going to build itself, as we don’t have that many good choices.
First, who doesn’t like drawing cards? So, were going to do our best to draw cards. Obvious ones, which see plenty of play in normal EDH include [scryfall]Mulldrifter[/scryfall] and [scryfall]Elvish Visionary[/scryfall]. Those are automatically in. If we’re playing Mulldrifter for bouncing, not to evoke it, we should probably play [scryfall]Gryff Vanguard[/scryfall] as well. [scryfall]Kavu Climber[/scryfall] on the other hand is probably too expensive, but we’ll use it anyway. [scryfall]Citanul Woodreaders[/scryfall] are pretty expensive, but works well enough in Pauper, and it has the option of not kicking it. [scryfall]Merchant of Secrets[/scryfall] is pretty inferior to [scryfall]Elvish Visionary[/scryfall], but since we’re just interested in drawing cards, we’ll use it too. [scryfall]Striped Bears[/scryfall] seems pretty expensive, as it isn’t as good an attacker as the previous fliers, but hey, we’ll use it too, just for consistency. [scryfall]Multani’s Acolyte[/scryfall] works well for us, because we can bounce it before needing to pay the Echo cost. [scryfall]Thalakos Seer[/scryfall] triggers from leaving the battlefield, which is somewhat inferior for our purposes, but works well enough. [scryfall]Wirewood Savage[/scryfall] is an open question at this point. Do we have enough beasts? Not sure. However, I should not that card, because I’ve been thinking about a [scryfall]Krosan Warchief[/scryfall] deck as well. On the other hand, our commander is a Frog Beast, so the Savage is in. Also, we musn’t forget our favorite snake elf druid, [scryfall]Coiling Oracle[/scryfall].
Bouncers include [scryfall]Man-o’-War[/scryfall], [scryfall]Aether Adept[/scryfall], [scryfall]Aethersnipe[/scryfall], [scryfall]Surrakar Banisher[/scryfall], [scryfall]Mist Raven[/scryfall], [scryfall]Vedalken Dismisser[/scryfall], [scryfall]Voidwielder[/scryfall], maybe [scryfall]Dream Stalker[/scryfall], [scryfall]Shrieking Drake[/scryfall] and [scryfall]Keymaster Rogue[/scryfall], but those only bounce our own creatures, which might not be that bad, because we really do love that effect, and maybe [scryfall]Hunting Drake[/scryfall], but that might backfire every once in a while. Gladly both red and green are pretty popular in Pauper.
Of course, we need ramp as well. Of course [scryfall]Wood Elves[/scryfall], [scryfall]Sylvan Ranger[/scryfall], [scryfall]Farhaven Elf[/scryfall], [scryfall]Yawimaya Granger[/scryfall] (which we don’t even need to pay the echo to if we have [scryfall]Specied Gorger[/scryfall] in play), as well as [scryfall]Borderland Ranger[/scryfall], [scryfall]Civic Wayfinder[/scryfall], [scryfall]Pilgrim’s Eye[/scryfall], [scryfall]Gatecreeper Vine[/scryfall] and the bit more hard to use, but still very synergistic [scryfall]Fertilid[/scryfall].
Journey Into Nyx brings us plenty of new tools. All the Constellation creatures trigger themselves, so we can use them freely. Not that many of them are common, but still. [scryfall]Humbler of Mortals[/scryfall], which not only feels right namewise in comparison with the epic name of the commander, but has a very good triggered ability, is in. [scryfall]Oakheart Dryads[/scryfall] feels weak, but we’ll try it. And well… sadly that’s it. Only two usable constellation creatures at common. Although, there’s a third one, which mills, which might actually be good at times, since there is some tutoring and recursion which might put cards on top of a library, but I don’t think that’s such a worry that we should be considering it as a possibility.
Evolve and Graft
We can use most of these. Maybe not [scryfall]Simic Initiate[/scryfall], but the others are all good enough here. Not sure all of them are good, but since we can bounce certain creatures over and over again (for example our commander), growing even the smallest ones is pretty easy, even though slow. Also, these two abilities work well together and with monstrosity, as giving certain monsters for example flying (with [scryfall]Helium Squirter[/scryfall]) is very good.
Oh yeah, we can’t be all about value. We need to actually be able to win. Of course, our commander is pretty good at this. [scryfall]Nessian Asp[/scryfall] is another great option, especially with Reach. Theros block has plenty of good creatures for this purpose. [scryfall]Ravenous Leucrocota[/scryfall] is also pretty good, as is [scryfall]Vulpine Goliath[/scryfall]. Even [scryfall]Cloaked Siren[/scryfall] is probably pretty good.

Simic Growth Chamber
I added some other value creatures as I just didn’t have enough before. Not that I don’t have any non-creature spells in the deck. This is just because we want to abuse our commander and also I just like to put that kind of limitations on myself. However, if you want to be more competitive, I’d suggest putting plenty of fight cards (like [scryfall]Prey Upon[/scryfall] and [scryfall]Time to Feed[/scryfall]) into the deck to control the environment.
Also, I didn’t really think the manabase through. Its just pretty much based on the fact that we need more green sources so that we can use all the ramp to get blue if we need it. Also, the deck has some more green cards, but I didn’t actually go through the casting costs and make actual calculations on good numbers.
