People talk crap about Dustox but I've successfully used it in Hoenn all the way through the elite 4 with no issues. Just gotta know how to use your favorite mons.
Platinum was the first Pokemon game I played for DS, and it was so addictive and amazing. I had an overpowered Empoleon, a Luxray, Rapidash, Steelix, Gyarados, and a few other awesome Pokemon that made me feel so cool. The game was so great and the storyline an adventure was amazing. I'll never forget that experience I had. I hope you enjoy your gameplay as much as I did, friend :)
What Are you talking about empoleon is the best starter, infernale fucking bodies. Is it as durable with as many resistances? No but does it best out empoleon in being able to glass cannon ohko other mons? Absolutely. The thing even hits empoleon for super effective.
