No
yes
The Sinnoh League Champion "Cynthia" has a Spiritomb.
Yeah, there is one pair of swimmers between Sunnyshore city and the Pokemon League. It's two swimmers and you have to double battle and one of them has Lumineon.
use a master ball if you haven't got any u cant
Lumineon is a Water type Pokemon that evolves from Finneon at level 31. It is not known to evolve into any other Pokemon as of generation six.
Im not sure but u can catch krabby during swarm.
If you really want to, use your masterball because it never fails. Masterball fails on other peoples Pokemon. I learnt from my mistakes... you cant catch trainers Pokemon it wont work with any type of poke ball(it would've been cool if you can catch trainers Pokemon though=)
No, unless you have a National Pokedex you might find a trainer who has one in the Battle Tower.
An Ace Trainer in Victory Road on floor B1F has one. Sorry, scratch that, the Metang only appears in Pokemon Platinum.
Nope, at least not in the story line. If you meet a player via wi fi or online then possibly.
