Of course warriors are strong, they have a lot of support cards. But in my opinion, they aren't the most powerful type in this game. Have you all forgotten about Armed Dragon, Dark Armed Dragon, Sacred Phoenix of Nephthys (not sure if it's a dragon), Horus LV8 the Black Flame Dragon, Judgment Dragon, Prime Material Dragon, Stardust Dragon, Slifer the Sky Dragon, Winged Dragon of Ra...?
I'm sure you will recognize these monsters as some of the most powerful monsters in game (if not the most). Of course they may have few less support than warriors, but as single monsters, they have the most devastating effects. But I would accept tying them with warriors, because the banned chaos monsters, which seemed to be the most powerful playable cards, were a dragon and a warrior.
Rollingthunder, I dare to say that in your type-themed tournament, the type which will have the advantage, will be those types which have their own searchers (fairies, dragons, beasts or zombies). I would wagger all what I had that the winner will be one of these.
Anyway, I'm not scared of them, and people who know me knows which type I'm going to use.
P.S.: Those who say that fiends are the most powerful type, could you explain me why do you think that? Thank you in advance.
