Some thoughts:

• 19 lands is way too low, imo try 22 and see if that helps your games.

• you have too wide a variety of creatures to get a consistent game. Figure out which ones best fit your gameplan and run full playsets of them. Being legendary doesn’t stop you from running 4-of in a deck!

Thanks for the feedback

I didn't see that i only have 19 lands, will add some to have 23

About the creatures, i still need to figure out which ones would be the most useful but will definetly keep in mind to focus on them

At a glance, I would say Predator Ooze, Renegade Krasis, Champion of Lambholt, and Cytoplast Root-Kin can all be removed. They seem like the weakest of the bunch.

Just to complicate things further, I think you should look to include Thrummingbird in the deck - it’d work very well here
