I know a lot of people keep preaching this "stall is dead" nonsense or "too many strong threats to stall" and it does get old, even for someone who religiously runs stall. Now, kan I can understand banning. He is superb against hyper offense as well as stall. Even mega lucario is a tough nut to crack, to an extent. I mean, it might not even be incorrect to say that stall is hurting a bit right now, but to the extent it has been said, this is nonsense. At 2% usage, I can't imagine all the people complaining about stall being 'dead' or non-functioning actually playing stall.
Even lucario can be stopped, if you're careful about it. I'm testing today to see if AV slowbro with a designated EV spread can take both physical and special lucario at +2. I already know he can take on physical mega lucario fairly well and the special side attacks have slightly less base power. Gyarados can hold his own for the most part as well, and I don't think he needs an assault vest to do so. Tentacruel hard walls special lucario, though I have to check how it stops physical luc (guessing not well). In all honesty, mega lucario is no worse than kyurem was last generation.
If anything, throwing in a fast revenge killer like last generation's idea of stall may help. Outspeed mega lucario seems a tad difficult, but a perfectly viable Starmie sits ready for stall to use, not only outspeeding, but resisting both stabs and providing offensive/spin support to the team. Need I remind you starmie has access to recovery? If you can do about 1/4 damage to lucario beforehand, starmie can guarantee a kill. And if you simply want to fake being timid and go analytic LO, you can OHKO with psychic after rocks every time (and have a 93% chance to do so without anyways). This gives you room to make starmie bulky while focusing on attack. Tornadus comes to mind with his 121 base speed and regenerator. He should OHKO with LO heatwave or just focus miss. With prior damage (approximately 14%) he can KO with super power, no LO needed. Support azelf can do the same, lead taunting, setting rocks and then using fire blast to target/OHKO mega lucario. Yes, it has to invest max speed (or near, at least) and max SpA, but Azelf's support slot is generally a fast variant for taunting purposes.
There are options, and some of the fast pokes even play support roles well enough. You just have to adapt a bit. I'm not sure what Lucario's suspecting will bring, I've already decided to try and help that one and give as unbiased an opinion I can. Unviable for stall? Not really, there is some adapting that needs to take place but when I build a team, I'm not looking to fit some mold of what is viable, I will make my team viable in itself.
