[Known/Fixed] Behold my completely legal and not hacked at all Swords Dance Shedinja

[Lugruf 50]

It seems that you can get a Shedinja with Swords Dance by evolving Nincada at level 41 and teaching Swords Dance to Ninjask as it evolves. This was possible in gen 3 and 4 but according to Bulbapedia was removed in gen 5. I guess that piece of game logic isn't updated in Reborn.

Interesting, though not entirely unexpected. I'm pretty sure you can see the occasional relics from previous generations like this in Reborn, so I'm not horribly surprised. Still, it's good to know that they exist.

This is known and should be fixed for E16.
