Hi, I need advice to make my team because I lose all the battles of arena and epic arena, I am level 65

You are at mid level, so by now you should have at least 5 strong Heroes. You could be losing because of the heroes you are using, or because you need to work on them. I recommend joining the SH Discord so players there can help you. A link to the server can be found in the SH subreddit.
