He's pretty good for dokkan events, but I don't think his team could beat any EZA aside from Kid Gohan's and Full Power Frieza's.
Then again, the game doesn't ban for using hacks outside of WT, so that's what I do for EZAs.
If you want, go to dbz space, to the apk section, and download the one that says HP.
Avoid the one that says "IW", that's insta win, and that can be detected. No one's gotten banned for using IW yet, but no reason to risk it.
HP hack has zero risks as long as you don't use it, or any hack, in World Tournament.
