Um?

Convenience mostly, also being able to know what stuff is popular. That's about it as far as I know though. (for people that are too lazy to even make a quick hack, imo).

I used to battle on Shoddy in gen 4, and PO in early gen 5.

Oops, typed wrong.:P
Anyway, do you know, what people like in a battling sim?

Make suggestion, or ask question?

Can I ask suggestion?

I didn't know the site owner wasn't around anymore. It's still up to date with Smogon's tiers.

Anyways, it's simple, really. Give it a single Poke, the tier you are using it in, and the generation you are using it in, and it will list every viable Poke in that tier, and why it either works, or doesn't work with your selected Poke, base on percentages.

Yep

Are you referring to Beldum Labs?

Looks like you use Synergy Pokedex. Mind telling me what it does? I may make it, as it's owner poofed.

Most of it is posted...Enough to start with, anyways.
