Copycat is a fun move here is why
It is a non sucker punchable move even after copying another move if using prankster liepard for example.
Copycat will target the # LAST MOVE OF THAT TURN (if its the next turn and you click copy cat it will use the last move of the previous turn)
the targetting will only randomly hit your opponents so you cannot copy cat and side pollen puff from it
Copy cat also can get cancelled out by taunt. So please position your copy cats better
A funny copy cat strategy is actually a mon using boom burst than sylveon using copy cat which is pixilate boosted
Copy cat is only in the following evolution lines
Wigglytuff, mr mime, Jynx, Eeveelutions, clefable
Delcaty, Plusle/minum, spinda, sudowoodo, lucario, mespirit, mimikyu, marshadow, dubwoo, maushold, squawkabily and flamigo!
Try to incorporate it into your team maybe! Its a very fun move!
