First,get into battle with anyone. switch to the pokemon that has the attack you want to use,attack,and switch to a different pokemon while it says "Please wait" the pokemon you switched should use that attack. (this could've just been a fluke,please don't post mean comments if it didn't work for you) example: I was using my totodile,when suddenly,I switched to my Shiny Suicune on accident. then,Suicune used Scratch attack on the Growlithe I was fighting,That was Totodile's attack,and Suicune didn't even know the move. on the battle log, it said: "Suicune used Scratch! 50 damage."
