Introducing.... M-Lickilicky the Wallbreaker! Dat 110/120/120 bulk is really good at making sure M-Lickilicky survives things, but 115 Atk is... meh. That is, before you realize it has Sword Dance. And Earthquake, Rock Slide, Gyro Ball, Zen Headbutt, Knock Off, Fire Blast... amongst other things.
However, not all is good for Mr./Mrs. Longtounge, because things like M-Venusaur, M-Meta and Nihilego anihilates it. And because of the choices, it has serious case of 4MSS, maybe more than M-Metagross! It has to settle between Slack Off and Sword Dance and the aforementioned moves for 2 slots, so... yeah.
*SETS:
