Last question I PROMISE. How do you teach a Pokemon a move it has a high enough level for, but it already surpassed the level required to learn it?

by using move relearner :d

How do I get it?

You can buy it from the shop under health items. The name is Move Relearner and it costs you just 1,000 gold. I never used it, but i think when we use it (relearner), the pokemon forgets every move that it has learned. Then your pokemon will remember every move from level 1, and you can teach any move you want from start.

the move relearner just lets your pokemon learn any move you can learn by level up that is before the level the pokemon is at. it will allow you to learn a move where you may have accidently clicked you didnt want ur pokemon to learn.
