"My Pokemon forgot a move mid battle and still used it."

So today I got an answer to a question I didn't know I had. I was in the middle of a double battle with my Muk and Raichu. I had Muk use Rock Tomb and my Raichu use thunderbolt. Obviously because he's faster, Raichu went first and knocked out the opposing Pokemon, which caused my Muk to level up. My Muk then wanted to learn acid armor. Out of curiosity I made Muk forget Rock Tomb for Acid Armor. After he learned acid armor, Muk still used Rock Tomb even though he no longer knew it! via /r/pokemon http://ift.tt/2giwa7t
