What’s the most NEEDED judge call you’ve ever had/seen

About a year ago, right when SHS got popular again, my opponent summoned Accel Synchro Stardust Dragon. Upon its summon I chained Nib, which they chained Accel to.

I had never had this interaction before, and Accel’s wording was confusing me at the time, and the opponent was doing a horrible job at explaining what should happen. My locals doesn’t have a designated judge, so they went to ask their friends how it’d resolve.

They ruled Nib would tribute the Stardust Dragon that was summoned by Accel, because they couldn’t synchro summon after it was summoned, so it didn’t get Accel’s protection.

This is the WRONG ruling, because Stardust’s summon is treated as a synchro summon and gets Accel’s protection from it, but at the time I didn’t know that, and apparently nobody else read the card right.

(Don’t worry I lost that game)
