Don't Know Me, Huh?

Hard feelings?

Hahaha, nice work, dude.

That aside, looking up the stats for the new Rotom forms, they have improved stats compared to the original form. Almost makes it seem worth using in a competitive sense. I don't have Platinum though, and I don't plan on getting it, so I suppose that won't happen.

Me? Copy you? I've only had that Togekiss since about a week after the game came out.

The party that I was working on before I stopped playing was Gardevoir, Leafeon, Breloom, Ninetales, Togekiss, and Spiritomb.

That isn't entirely true. Breloom is one of my favorites in 4th gen due to his great movepool and nice stats. It's a physical attacker in every sense of the word. Same goes for my Leafeon.

The rest being special attackers is just a matter of preference.

I did, about six months prior to her.

In the first two generations, I always go for grass. In the third generation, I pick Mudkip or Torchic, most often Mudkip, and fourth gen Piplup.

Tangrowth, on the other hand, is pretty balanced overall-- but even though its base Special Attack is higher, it doesn't get very many Special attacks to work with. However, it learns some pretty nice Physical Attacks. What I would do is give it Toxic, Swords Dance, Power Whip, and whatever move you want as a fourth.

You COULD also play to your advantage with its Ability (preferably Chlorophyll) and teach it Sunny Day, Solarbeam, and two other moves. This would double its speed while utilizing its high Special Attack stat. But that's just so...uncreative.

One thing to watch out for is Tangrowth's lousy Special Defense, which leaves it wide open to pretty much any of its weaknesses. You might want to counter that with Sleep Powder or Double Team (or both! Use Sleep Powder and use Double Team a bunch of times).

Of the three, Honchkrow has the highest physical attack, and the highest attack overall. However, due to Honchkrow's affinity with Special-buffing moves like Nasty Plot and Calm Mind, I'd suggest teaching it special moves instead. Believe it or not, Honchkrow's max Sp. Atk is higher than Xatu's. So if you boost with Nasty Plot or Calm Mind a couple of times, and unleash with Dark Pulse or Psychic or Shadow Ball (last two can be taught by TM), and balance it with a physical attack like Night Slash, you'd have a fierce sweeper on your hands. Of course, where Honchkrow falls short is its lousy defense and special defense stats. If you use Calm Mind instead of Nasty Plot, your sweeping potential would be delayed, but you'd fare better against special moves like Thunderbolt or Ice Beam. Because of Honchkrow's overall superiority, I'd drop Xatu from your list altogether.
