Your curve is way too high to only run 21 lands. I would either drop some of the higher cost creatures or else add lands and some decent ramp. Personally, I think Archetype of Finality , Hythonia the Cruel and Keepsake Gorgon are all pretty mediocre. I think you'd be better off with smaller, faster creatures like Lotleth Troll and Boon Satyr . Three Vraskas seems like too many. I would drop 1 and add a land. I'm also not sure Gaze of Granite is really worth it, especially when you have no ramp. Since you already have plenty of spot removal, I would swap it with some card draw, either Commune with the Gods , Grisly Salvage , or Read the Bones .

for ideas, you can also deck out my standard vraska deck:

maybe consider cutting the archetypes for a pair of polukranos

I like the suggestions, but this is suppose to be a gorgon theme. Removing the gorgons would just turn it into another golgari midrange

If you want it to be gorgon tribal you should probably put that in the description. I thought this was supposed to be just another golgari midrange

Not bad man, but id drop the Hythonia the Cruel and add 2x Pharika, God of Affliction yea a 4/6 deathtouch and a non-gorgon board wipe is sweet but for 6 then 8, ouch. Your avg cmc is already a little high anyway. Id also drop the two Pharika's Mender and throw in 2x Nyx Weaver lower mana cost and its any card way more useful.

I would try to find some room for some ramp. Either a playset of Elvish Mystic or Sylvan Caryatid

Honestly, this deck should be kicking ass. Your removal package is down cold. The only thing I'd do is ditch anything 4 CMC or higher, replace with Sylvan Caryatid, and Courser of Kruphix. Reaper of the Wilds backed up with your removal package should be winning the whole game for you.

or instead of Hythonia the Cruel you use Kalonian Hydra

Ok, I did a quick update what do you all think now?
