Photon Booster | Decks and Ruling

Why konami decided to add this card in this event? It has no sense... This card is too specific: its single utility is to summon galaxy eyes photon dragon. I think there shouldn't be other reasons this card exists

this + servant of catabolism = 🔥

I think there is a glitch that can be used with this card or this player, named l.k., hacked something. I sat a sylvan mushroom on turn 1, he played no cards on turn 2. I attacked with w. carrot on turn 3. Turn four...wow...he plays plasma ball, then plays photon booster. Next he equips backup rider, then plays cosmic cyclone, losses 1000, and destroys backup rider. Then he plays photon booster again. He attacked and it did 7000 worth of direct damage. Photon + backup rider is 3500...how the hell did he double his attack? How would two photons do that? Either the card is glitched or this l.k. player has hacked something. But, more weirdness, I was then given Dlv 17 for only 2 wins with 2 losses immediately after playing this guy.

This + Ra's Disciple = 3 2000 Atk Monsters in one turn
