if your asking for my kind of theme well i really like fiends in fact i most of my cards in my trunk are fiends. I would like to make an archfiend deck but i do not have pandemonium i lost my only one. dark world are cool too but i dont have goldd or silvva but i do have the rest but only one dark world lightning. I think i have a thousand cards in my trunk so i cant list. warriors are cool too i have silent swords man 3 and 5 i like them alot, but i have no use of them in my deck without 7. i do have quite a bit of harpie cards and wind but i tried it out and it didnt turn out well. My deck is pretty good right now but if i theme it will it become better?
