Advantages and Disadvantages

Team Twilight Members:
Advantages:
can "Snatch" NPC trainer's pokemon and have a better Haggle success rate.
Disadvantages:
The chance of a shop owner kicking them out is higher. The "Snatched" pokemon won't obey a single word they say and will often attack them unless crystalfied(Whatever you call it xD)

SOJ Members:
Advantages:
Get a small discount on purchases in pokemart(100 poke), can steal back "Crystalfied" NPC pokemon.
Disadvantages:
Cannot Haggle at ALL, "Crystalfied" pokemon have a high chance of becoming confused in battle and contests and often hit themselves and take more damage than usual in all attacks. (Note, Crystalfied pokemon cannot be normal until the soul stealing process is reversed.)

Normal Trainers/contest coordinators:
They are neutral, they get no advantages and no disadvantages.

Breeders:
Advantage:
They get to be hired by The Day Care and receive pokedollars for each pokemon they take care of, so more poke income. They can bring along up to two(or one) extra pokemon with them(Meaning 8 pokemon can be brought total)
Disadvantage:
Pokemart prices are upped slightly(by 200) they CANNOT use another trainer's pokemon in trainer/TT/SOJ fights! They can fight wild pokemon, but they cannot do any more battles than that.
