New to BGA and want to get good.

Guys. I’ve been thrashed last 5-6 games of arena. Lost every one. I have about 25% win outside of arena. I would love to get better. Where are some good resources you used to scale a little quicker?

In my games I feel like I am neck and neck but then lose suddenly. I’ve tried leaning towards smaller animals - as I’ve noticed early appeal is a must. What are some realizations to help me?

Also, is this game like chess? Do I need to get premium to study my stats, etc?

When I finally do win one game what do I gain in arena? As of now I’m just bronze 0/10 stars lol…

I want to get better! How!!!
