I abuse the Mimic glitch to teach Pokémon moves that they can learn by tutor moves instead of using a XD rom I asked you about earlier, yes.
#1, the Pokémon in question is able to learn this move by tutoring, it's not an game exclusive move pokémon that can't be RNGed (ES Linoone and BP Zapdos for example)
In my eyes, it is a huge difference
