If you thought that Axie was good but eth was bad due to fees, certainly someone else had the same idea. Introducing https://www.karastar.com/
So, Karastar is an Axie clone but on BSC. Just as expensive, but with far less gas.
Similar aesthetics:
Blobs with some features.
Similar gameplay:
I get cards based on the Kara's moveset, and I can play them.
Similar rewards - UMY instead of SLP.
Also an energy system just like Axie.
The game is rather new, and full of bugs (you can see ARENA misspelled clearly.)
As for cost: floor karas cost 0.29 BNB as of this posting, I got most of mine at 0.2.
Minor stuff like their whitepaper, token distribution stuff:

(No, it's not up to date either.)
UMY per day on a fresh account is about 27-30.
After reaching level 5, that becomes 45-48. (About 5 days I think.)
Anyhow rewards increase until about 100 UMY from PVE, and unlimited (but based on energy) from Arena.
Arena wins are 3.75 per match.
With these rates, I think it pays more than Axie.
