I'm currently versing lvl 45 duelists and none of my decks can beat them and all the decks I've tried to look up and make have cards in them that I don't have. I'm stuck now since I can't beat any of the duelists what should I do>
If you have metalmorph use it. I USE 2 because they pop out strong monsters. Use a michizure trap, Riryoku a must, mirror wall half shut etc... Anything thats a good defensive trap/spell.
Also use a skill that is pssive like LP boost. Hope all this helped... I dont know what cards you have but use your strongest monsters and defensive traps. Dont waste your time with trap jammer and twister really not needed...
