Post your replay as proof of your outrageous claim. All replays are time stamped and have the rank up information if applicable (which it would be in your case).
It's not the first time either that people try to pull 🔥 on Gamea. Just recently, a few months ago, there's someone sending an Aromage Synchro deck as his KOG deck, and advising to use Ancient Sacred Wyvern like him to overpower the opponent.
Which is all good, ASW does synergize well with Aromages....except his deck runs ZERO Light Tuner. You need a Light Tuner to summon ASW.
if you're familiar with room 1, mayaya reached kog with aromages last month as well. late season kog but it is doable. however, the tuner issue posted here sure is questinable.
