This deck has a lot of cool ideas, but it is a little bit all over the place. I think you can optimize it pretty quickly with a few changes and make it very strong.
For the combo plan - Arixmethes goes infinite with both Freed from the Real and Pemmin's Aura (infinite green mana) and a 1 card combo is a lot more efficient than the 3 card combo Animation Module. I also think that Deadeye Navigator is a great option for your Cloud of Faeries and Peregrine Drake infinite mana combo. I also think you need a way to win once you generate infinite mana. You can solve two problems at once by including X draw spells like Stroke of Genius and Pull from Tomorrow. Adding Thassa's Oracle or Jace, Wielder of Mysteries can give you an instant win after drawing your whole deck. Another good infinite mana combo for your deck is Kinnan, Bonder Prodigy and Basalt Monolith. Both cards are good in your deck anyway because you have a ton of permanent based ramp for Kinnan and it is an infinite mana sink. Basalt Monolith is just good ramp that sometimes goes infinite.
For the non-combo plan: I think your instinct to cut out the +1/+1 counters theme is a good one. It doesn't really fit with what the rest of your deck is trying to do which is ramp and play big threats. If you really want to keep it, or even if you don't, Hydroid Krasis and Prime Speaker Zegana are really good card for your deck as a threats and card draw. Your commander gets you straight from 4 mana to 6 or 7 the next turn, so I think your threats should be around that mana. Nyxbloom Ancient seems great for combining your mana doubling theme and your big mana theme. Just put in your favorite big creatures and have a blast.
Overall - I think you have a really fun deck on your hands, and you can optimize it with just a few changes. This is just a suggestion, and there really are a million different ways to go with Arixmethes so do whatever you think is the most fun. My last piece of advice would be to cut out a bunch of the tapped lands like Simic Guildgate. You are a two color deck, so you shouldn't have a ton of trouble getting your colors especially with all of your ramp. Basics will make you a turn faster.
Have fun brewing up this deck. Best of luck.
for the most part I'm just playing paper, so that's why all those tap lands are in there, just don't have the better stuff lmao (dislike blue so generally trade off my blue lands) will probably replace
simic guildgate and
woodland stream and maybe the 2 cycle lands that I left in with those if I find some of the cheap ones (especially cheap duals cuz
wood elves is funny)
I'll have to look and see if I have a
freed from the real cuz that's probably gonna go in.
I only have 1 nyxbloom and it's significantly better in my elf deck and I can not justify spending 20 dollars on individual cards personally. Same thing with deadeye (altho I might trade for it, so if I do that I'd do it) and the
zendikar resurgent and pemmin's recommended by cosmic
I do have a
vernal bloom somewhere around here but I can't find it for some reason (very funny card lmao) that also works to go infinite so
I was actually looking for some draw x cards and I couldn't find them, the only one I had was finale of the infinite, if I find some I'll try to nab them though
why is kinnan only 7 bucks wtf? that's a 2 mana mana doubler smh might try to find that
ALSO some things I am wanting to add is
soul of the harvest (only have 1 and it's better in elf)
primordial sage (I might have another of these lying around and if I do...it's going in) and the 3 drop one from ixalan (I'd need 2 cuz it'd first go in the elf deck)
also yeah, I don't have an
ashnod's altar either so
animation module isn't even really comboing at all, it's more just something for me to put mana into with
durable handicraft currently
I REFUSE to put in any of those super common wincons in the form of lab maniac,
thassa's oracle, and the jace as....it's honestly just boring,
biovisionary +
rite of replication is also boring but at least that's not really the only way I will do it with
biovisionary (progenitor maniac) so....it's borderline rn
most of the combos currently are bullshit as well, honestly not trying to make this deck super good as...good combo decks aren't fun to play against generally,
freed from the real is borderline for me currently as it's only infinite green mana which is significantly less useful, and
basalt monolith is the same deal with colorless.
prime speaker is another one that is probably gonna go in, it's still good without the combos so (pretty much just the same as
rishkar's expertise or ...
ALSO if I do find another
helm of the host and a
timestream navigator let's just say people are gonna have a funny combo I've never seen before at least (infinite turns)
