So I got a shiny Salamence off of Wonder Trade with the moves Dragon Sance, Dragon Claw, Iron Tail and Earthquake. I accidentally made it forget Dragon Dance, so I went to the Move Relearner on Mt. Lanakila and Dragon Dance wasn't on the list of moves Salamence could relearn! I looked online, and it says Move Relaearner can relearn forgotten egg moves. Is my Move Relearner broken?
