Level doesn't matter that much in this game to be honest. Not saying it's not important, because as you level up you get more BP / Vitality / Deck Cost, but it's not a decisive factor.

I stalked visited your kingdom and saw you only have 1 Yggdrasil but your Magic School is already level 7. You should really consider buying the other 2 Yggdrasils before leveling up your Magic School again (because you'll need 2400 Jewels to get another BP out of it).

Upgrading your elemental buildings would also give bonuses to your cards, so you should do that too when you have resources available.

About your ATK Unit, it's good. The only problem I can see is that SR Ensemble may be too frail. Try to awaken Huang Long (and Ensemble after you get her to HSR).

The DEF Unit though... For a defense team you want cards with skills that deal damage to all enemies (turn skippers are also a good option), so Princess Iron Fan and White Night shouldn't be there. Can't really comment on Diaochan since I don't use cards with that kind of skill but being an UR she probably gets killed easily.

That being said, defense really isn't that important so it's up to you if you want to change it or not.
