only about 14k atm. I also have Silver Sonya and Silver Kotal Kahn but they're both only lvl 7. Are either of them good? oh, and i also have a lvl 21 silver reptile but idk if hes that good^ Stop using Kano, he doesn't have a useful special in my opinion.
I think he has bleed, but Power draining characters are so much better.
How many coins you have? I suggest you pick one or two characters and try to fuse them together if you can.
