New to Splinterlands

Hello out there everyone! I'm just getting into Splinterlands, and I really like the concept so far. The games are fun, and there's a good amount of variety.

I've been playing ranked, and I'm really struggling once I get past novice into Bronze III. What tips do you have for positioning, and what type of cards do you think are best at this level?

Also, I'm curious your take on the current market and what you think the future holds for the game as well. Thanks!
