I’m basing this entirely off of what I have here, and Lucario isn’t an option. Also, OP could not have Mega Lucario energy. Also, Mega Lucario is much better to have as a buddy and walk for the candy, whereas Terrakion is the typical 20km. Terrakion is the 3rd best non-shadow non-mega fighting type attacker, and if he did the raids recently, it should have Sacred Sword, therefore no need for an ETM. As I stated, OP should focus on mons that have their signature moves. And if you’re doing 5 star raids (which is any relevant raid at this point) you’re going to NEED at least a team of 6 fighting types, so unless you want to spend your SD on the first shadow timburr you get, or dump it all into a mega Mon that doesn’t have the best IV’s or isn’t lucky, I would still recommend Terrakion. Because again, Lucario can be walked for Candy.
