Flame Orb isn't optimal for Quick Feet physical attackers, because their Attack is still halved.
Flame Orb is preferred over Toxic Orb ONLY for special attackers, Guts, or Flare Boost.
Shadow Pokémon are from Colosseum/XD, and are presumably impossible to code into Gen 6 hacks. The bigger question here is why anyone would think to ask whether a Gen 6 hack included them.
