I would switch the Pyxis againt a Grindlock, it gets you there faster if you survive a few turns just building the counters on it.

I just added a description, sorry it wasn't there when you commented. The Pyxis is the big win-con, I think without it you would be relying on the Phenax, which is only a one-of. Besides, the Pyxis is super fun to play!

Neat deck! You can add Monastery Flock in your list of wall to deal with flying creature. I don't know what to swap out tho

I agree about the Monastery Flock. I think I will put it on the SB for opponents running lots of flying threats, like Sarkhan and Stormbreath. I think that I can't quite fit it onto the MD just yet (although that might change based on the meta) as the Wall of Frost is better for toughness and devotion, let's see how it goes! Thanks for your help :-)
