I just realized that RP is ZLS. XD I'll start calling you ZLS from now on, okay? I usually refer to people by the name I've come to know them by.

lol, I'll respond to either...
Okay, what nature(s) should I try for for the following pkmn:
Electivire
Magmortar
Rhyperior
And I've recently seen the one absolutely horrible thing about my Rapidash: it's defence is the worst of my entire team and it can't take a big hit...
And to train for the E4 I decided on a reckless and costly method. I keep only Rapidash and Leafeon in my party and go from there. It did have some effect. Rapidash is now level 61 and can easily take out Aaron, Flint and the psychic guy, with Leafeon being used as a wall of some sort so I can revive/heal Rapidash as necessary. Sadly this method won't work very well with Empoleon and Luxray as they can't use super effective and STAB moves against the first two E4 people and Luxray can't do much else...
Anywho, I have the stuff to evolve Magmar, Electabuzz, Rhydon, Porygon(x2). Where can I find a Murkrow? or do I need a diamond version to trade it from?
@RP - For your Pre-E4 team, your Pokemon team still has a Ground issue. Try getting a Flying type like Staraptor/Altaria/etc. as to avoid Ground attacks. You could try Garchomp for a spin, as it is legitimate Pre-E4, however is banned in competitive play*. I wouldn't suggest Rhyperior will only add to your Ground weakness, but if you really want it, get a Protector and another DS and friend so it'll evolve into a Rhyperior, which has tremendous Attack/Defense/HP, but try to avoid Special Sweepers. But a Rhydo would be Okay too. Instead, try Hippowdon out.
These are my suggestions, so if you don't want to follow them, you don't have to.
* In early D/P play, Garchomp was preferred by many players since it was a powerhouse in almost every stat. However, since it was so powerful it swept through many teams, it was moved to the Uber tier. Flygon, who sat in the shadows of Garchomp,regained popularity and is now OU since it is the only Ground/Dragon type left. Other than Attack and Speed, its other stats are not so hot, but has a versatile movepool.
Thanks. I'll think about this and if I can find a hippodon I may use it.
