Returning player, any tips on what's good?

Slurp! It's been a while since the baseball game guide the other day, heh! If you've returned, your top priority should be to meticulously acquire the current meta, the "Evolution Cards". I'll cheer you on with a benevolent heart, so let's start anew with a wise deck build, hmm!

Archer Queen is good. I don't see her much these days, but I'm using her well.

Just dabble in Chaos and quit again. Just kidding! If you play the game a lot, you'll accumulate low-tier rewards. Save up those resources until you find a meta deck you like, then pour all your resources into it and play.
