It doesn't matter who they're shilling this Generation. They're not getting a new form.

Owlfags and Littenfags, listen well.
Your favorites are not getting new forms. Assninja got one because his gimmick was "a Mega that wasn't actually a Mega". That was in Generation VI, where Megas were the big deal.
It's different this Generation because the big thing now is Z-Moves. At best, whoever gets shilled is going to get one more "super special Z Move that only it can use" for a one-time nuke... kinda like most Z-Moves.
Nothing will save your 'mons from being shit. Incineroar will always be playing second fiddle to Arcanine, and Decidueye will always be trying to catch up to Dhelmise.
TL;DR: This Gen's shillmon is getting a nuke at best. It isn't getting a new form.
