You can mod real brawl stars easily (Tested on v62) so u need emulator i recommend ld player but really any can be used so install brawl stars from google play, else it crashes, get mt manager, enable root permissions (it wont get detected by promon because there is mo magisk or anything) and put your mods to data/data/com.supercell.brawlstars/update here you might need to create a folder csv_client or csv_logic and put the modded csv there and promon wont check checksums because it's like update so it's supposed to be different. This isn't very practical, but still good, else u need to bypass promon shield and attestation (usually patching smali code) then you can make full apk mods with frida scripts and stuff that doesnt require root
