MKX Mobile is very hackable, I stopped playing now because I maxed everything. You can modify XP to max out level 50 cards, using Lucky Patcher is easiest for unlimited Souls/Koins, you can also modify health and damage although for those you want to create a modified APK. I have decrypted ini files for full online/offline character, skin, kombat kards and dlc unlocks for the retail steam pc version if anyone is interested let me know.
