i think you can exchange fireyarou with flame cerberus, since fireyarou doesn't have an effect at all... and why do you choose eternal drought?? i know if it is for destroying fish, but fish monsters are so little, so they don't appear too much on the battle, unless your opponent make a fish deck... so i think you can exchange them with cheap magic card, like paralyzing potion or megamorph... then, you choose magician of faith, what cards do you want to revive from it? magic jammer?
maybe it's not related to your pyro deck, but maybe you can use fire reaper for destroying cards on the meadow... --- How do you prove that you exist? Maybe we don't exist... - Vivi Ornitier
I'm currently running a Pyro deck as well. Personally, I think there are too many weak pyro monsters there, you can stick only with 3x Molten, 3x Vermillion, 3x Flame Cerberus, and 2 Fire Eye and/or 2 Dragon Piper.
As for spells, as mentioned above, Eternal Drought is kinda useless. Shadow of Eyes is meh, l'd replace it with Dark Hole / White Hole combo. If you rely on Yellow Luster Shield, consider adding at least one Shield and Sword. One or two Paralyzing Potions can be handy. And Mirror Wall is just overkill...
But anyway, this is my style... --- I will not change this sig until Claymore is published in my country !!! (11/29/2007).
