My Larvitar from the community day evolve to a Tyranitar and he didn’t learn Smack Down, if i give him a MT. He could learn Smack Down?
No, Smack Down I’m afraid is only attainable during those 3 hours of Community Day. TM’s wouldn’t work anyway.
Sometimes they dont get the exclusive move. it’s unfortunate.
You had to evolve him during those 3 hours.
