Al Custom

What is that Al Custom means? And how does it work?

You can control it completely by using the Client API.
Can use this wrapper:
Duelists Unite / DuelBotWrapper · GitLab
Or use it as a base and write your own in any language you want.
The API end-points to control it should be quite simple to understand by simply looking on that C# Wrapper for it.

I’ll try it.

Sweet, so make a video and I’ll explain it.
