Nightmare Dichroic
Appearance: when the light die down, a black dragon with several blue-colored crystals embedded on its body and had one right eye red and the other blue appeared next to naruto and the dragon body letting out a soft dark glow

that means that naruto will have fusion monster along with ritual monsters since if you do it I will gladly help you create them and it was good that we had a chapter without naruto duel since that shows that you will give other characters time to shine and it was also a very good chapter.
and you will also give phantom synchro to naruto or assault mode to naruto to evolve their monsters:

the story continues being too interesting to leave it hanging

i quite enjoyed it, some would be upset about the lack of the main character (Naruto) not in the very least commenting to himself or to other contestants but i for one see the reason why you didn't do so. it was because you brought as new character in and just as the first chapter did for Naruto so to did this one do for Wolfe. you presented a overall showing of their personalities, abilities, duel styles, and decks.

The premise is good. I hope you continue this story soon

Hey not bad so far. I’m really looking forward to see where this goes. I got a good feeling with the way Naruto’s deck works his ace will be Rainbow Dark Dragon

I’m cool with my only issue is that they to many decks to make one up

interesting and intriguing, I can't wait to see the next chapters of this story, little tips you could use as decks the "beast gladiators" or "dragon-units"
