Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
You can get a special Electivire and Magmortor by using certain cheat codes. You can also get a special Pikachu from beating the game. However, you do not obtain any other pokemon from PBR. =[
I'd say I'm pretty good at that as well. I may not battle much but it doesn't mean I should be taken lightly lol. I also won an apprentice tourney a year ago.
Well, for one you should be using Adamant nature, since you will simply be abusing that monster attack, and you want to hit as hard as you can in that one turn you have.
Number 2, you need better IVs.
Number 3, run like... Return/Earthquake/Sucker Punch/Fire Punch. =)
In my honest opinion, Blissey should be Bold with 252HP/252Def/6SpD.
You do not need anymore SpD than that. If they can boost like crazy with Nasty Plot, EV's won't save you. Nobody uses Spec'd Lucario/Spec'd Gengar anymore either. :P
