OK. I wasn't sure where to put this, so I just put it here.
This has been bugging me for awhile now.
Say a Pokémon knows Metronome, like Togepi, and uses it tp bring up a sketch attack. Would the Togepi sketch the move that opponent has just leraned and, thus, know it itself?
If this is the case, would there actually be a possibility of a Pokémon knowing a move it can't normally learn without actually cheating?
