From what I have noticed while playing with this deck you either focus on the shurima side with Azir or on the shadow isles side with Kalista.
Both are viable from what I played.
Biggest weakness i noticed were dragon decks as your units tend to have low healt. Although if you can play the ruination of you might be able to make a comeback.
As this is the first deck I made myself (based it roughly on some older kalista/Azir deck on this site) I'm sure there are improvements possible.
