How does that duel arena glitch work?

[problems]

I was just wondering how those kids do that glitch where they can summon familiars even though summoning is off.. I'm just furious because i've been scammed out of a good 200m already from that same thing! idk y but i keep falling for it. I don't see any changes when i'm setting up the rules.... It just works...
How though?

There are many glitches in Duel Arena which are not patched. One "bug" can be performed several different ways. They may patch a way, but there are still other methods. Applies to various bugs.

Just stay away from Duel Arena atm. Too many bugs.
