Forum:Dragon Deck!

I was just wondering because I've been running a Dragon Deck for 1 year already. In my school a Fourth Year High School student made his own Yu-Gi-Oh clan. I'm just third year now. He said to join I need to beat him in a match duel. I beat him in three consecutive match duels. His running a Blackwing Deck. He said that my Red-Eyes Darkness Metal Dragon (I have three) is a combo breaker. In addition it swarms the field in a couple of minutes. He said it should be limited because of its effect. Please tell it shouldn't be limited and I hope KONAMI won't make it limited. If its limited, I will change my deck.......:(
