Looks like some more testing database errors got through the Sinnoh egg move update, most of which won't be testable until Pokebank (even if they all look appealing
) but connect to some of the past errors, like Switcheroo Klefki/Wide Guard Honedge.
Under Pre-evolution only moves for Gallade, Ralts is listed as learning Ally Switch through egg, which is currently untestable until Ralts that learned Ally Switch from TM in Gen V can be transferred over to XY. Likewise, Probopass has Wide Guard from Nosepass egg (untestable currently), and Froslass Hex and Switcheroo (past-gen egg move, but untestable without Yamask and untestable until Cottonee is available, respectively). Dusknoir and Drifloon also had Haze listed in their egg moves, which doesn't appear to be possible to test without Koffing/Yamask, unless there's a new chain not listed yet.
