In my latest run of Pokemon Diamond, I traded some Pokemon again for viarity. These are the Pokemon that impressed me.
I traded over a male Ralts with the male evolution stone. After it became Kirlia, I evolved it immediately to Gallade and taught it the 50 base power rock move I forgot the name off. Just with Slash + the rock move, it did wonders. It special defense was so insane early game, attacks bounced off on it. Once it learned Sword Dance at lv25, I am pretty sure I swept every thing until the 6th gym. At some point I kinda neglegted it from gaining experience because I had way to many team members to try out that it didn't live up to its full potential. It learned Psychocut at lv28 which is insane. I didn't even really need it to sweep the fighting gym since I could set up on any Fighting Type trainer and Sword Dance to +4 or 6 and sweep with just slash. Psychocut made things just faster. Then I just taught it the TM Drain Punch to give it the needed fighting coverage.
Hard to say how good it would be if I let it catch up with the battle for Team Galactic in Spiral Tower. With Close Combat I think it would do fine for the rest of the game but not so sure about the Elite 4.
I traded over a Ralts with Synchronize Timid Nature just for softresetting Dialga, Heatran and through Void Glitch Darkrai and Shaymin. I ended up grinding it to a point that only with Psychic, Calm Mind and Magical Leaf swept in many fights especially the elite 4.
It seems to be usually the case when I trade Synchronize Pokemon and use them Abra and Rals are good candidates. Natu fell off quickly. Maybe I use Espeon or Umbreon next tho I don't have hopes for Umbreon because its a defensive Pokemon and its offense are laughable.
For HM purposes I traded a Teddiursa lv20. I let if gain EXP through Exp Share so it can learn Rock Climb. This thing had already 80 base attack and did as well as it did in XD Gale of Darkness with just Strenght and Rock Smash. It fell off quickly due to me not grinding to much and limited coverage but as an HM slave it allowed me to swap with a lot of team members and focus exp on Pokemon that matter. In that way it did what it needed to.
