Just FYI, I am in no way a pro player, I just built this deck for fun.
Pretty much just relies on utilising support, spell and trap cards to get as many dragons out on the field as possible before your opponent can effectively counter, with a couple Red-Eyes Iron Knights in there to support the Slash Dragon's effect, which comes in really handy for cancelling out your opponent's spells and/or traps. The Archfiend is there more as a backup for destroying monsters with it's effect when you're in a tight spot. This is usually the deck I pull out when I can't win and it rarely lets me down, not counting bad luck on the draw of course. Plus I just love Red-Eyes monsters as a nice bonus.
