Howdy Smogon, hopefully this is the right place for this.
I'm currently doing an Emerald run where I'm aiming for all seven gold symbols in the Frontier and a long streak in the Tower. I haven't had much trouble getting the symbols (except the Battle Factory which is death) but the streak has been an issue. Then I saw the Trick lead/stat-uppers strategy people have used in Gen 4 and decided to apply it to Emerald. I plan on using Alakazam as the Trick user, with the logic being that it is very fast, can set up the appropriate screen, and won't bait Fighting attacks because of its typing (unless I'm misunderstanding how the AI operates), while Curse/Metal Claw/Sub/Amnesia Registeel and Sub/CM/Dragon Claw/Recover Latias would be the stat-uppers. Then I ran into a bit of good luck and found a 31/26/30/2/31/26 IV spread with a Careful Nature for Registeel, which happens to be HP Steel 70, a major upgrade from Metal Claw.
My question is pretty simple: how do I got about EVing this guy? I already caught him but having -10 base power from Iron Head sucks (and a slightly less-than-ideal IV), though the flipside is the Heatran doesn't exist and Magneton has less bulk than its evo. The spread I have currently is 252 HP/124 Atk/116 Def/16 SDef, which yields 364 HP/212 Atk/364 Def/374 SDef at level 100. Is this adequate, especially with regard to its attack power? (Is that enough of an investment?)
Thanks in advance. (I suppose that qualifies as a pun.)
