So, are there(or have there been) any Pokemon you're using for the first time and surprised you with their performance?

Have they become a favorite of yours?

>Mamoswine
Currently have one on my team in Platinum. I've never used a Mamoswine before and HOLY TITS. Sure go ahead, attack first, Mamoswine will just take it like he doesn't give a FUCK and pummel your FAGGOT ARSE with Avalanche.
