Is my party good and can i beat the elite four with 'em?

Pretty good, but not good enough. Tell you what. there is a glitch where you go to elite four. Have one pokemon slot free for cloned pokemon. Save game & turn off whe its still saving. You should get a duplicate. Im a Pokemon Master because I know how to get good pokemon. Now this is my best pokemon team: Mewtwo lvl100, Regice lvl93, Grotle lvl100, Rampardos lvl 95, Ho-Oh lvl100, and Dialga lvl99. I would gladly trade you my Lugia lvl99 & Zapdos lvl86 to beat the elite four
