Looking at the list:
- Leafeon must be evolved, cannot be caught otherwise. Eevee is only found from Bebe in Sinnoh (in fact, if you want some trivia, the Castelia City area is the first time wild Eevee can be collected in numerous quantities and can thus be considered its habitat). Levels are either 5 or 20.
Definitely a hack as far as I know After other research, it's legal.
- Camerupt and Numel are both found in Sinnoh;
http://bulbapedia.bulbagarden.net/wi...oute_227]Route 227[/url] tops out at Lv.53, but the
Stark Mountain Camerupt MIGHT be legit. as they appear there at Lv.55 (not Numel, which are lower). Shininess could be hacked, but there are some honest people even on the GTS (hey, you used it

), so I want to believe that is legit. Perhaps get me some moves data and I can tell you for sure whether it would be considered legit., or even have a Pokécheck done on it?
- Swellow is possible, from
Route 13. Wish people wouldn't waste their Master Balls on these, but I guess they're more worried about knocking it out.
- Rapidash is found on
Route 12. Level checks out.
- Drifloon sounds like a hatched Shiny from a legit. Drifblim or something. I'd be curious about the list of moves. Again, might not hurt to run a Pokécheck, but hatched Eggs always have a Shiny chance. If it wasn't a regular Poké Ball I'd call it a definite hack, as Lv.1 is extremely rare (I've seen Magikarp like that available, even Lv.100 of those and ironically in the same body of water).
-
Litwick checks out,
-
Blissey isn't even worth analysis Valid, see above.
Met at Lv.100? Seriously? I will check my Scizor, evolved from a cloned Scyther I caught in a SS Bug-Catching Contest, and get back to you on whether the "met" level changes when imported to another game; I do not believe it does (if it somehow does, that Dragonite suddenly could be legit., but I'm banking that it doesn't).
Therefore, move Leafeon and Blissey to the "hacked" listing (pending research on my Scyther). I should be back shortly to comment on this.
