Same thing was said about Inheritance, and stall dominated inheritance.No, there have been solid arguments for it, not just theorymonning. However, I completely agree that the opportunity cost is FAR higher here than in Ubers. It's roles don't completely overlap w/ Victini, as a matter of fact, they are really quite a lot different. Victini is a FAR better wallbreaker, but Pdon is better able to sweep and support its team. I feel that A is very much fair, considering its crazy bulk, vast number of support options, far superior defensive typing, and access to Rock Polish. Also, although you are right that this is small, but it does have a 70 BST advantage, which is a pretty big number.
I'm not so sure about that. Stall is limited by the number of available stones, but psychic types seem to be a dominating force for stall, and they are a threat to Gengar in themselves. I'm not dismissing your suggestion, but I'm just uncertain.
Also, I must say, I feel offensive teams will still be far more popular and dominating anyways, especially w/ cresselias banning. The options for offense are, not surprisingly, far greater than stall. Gamefreak just doesn't like stall, imo. Balance-balanced/bulky offense seems to be very good here. The problem is, there are so many things that hit like a nuclear warhead that it's really hard to fully stop many offensive threats, even for stall. Offense has to really play prediction well, otherwise you're screwed. If you mispredict and use the wrong move on a not yet mega-evolved opponent, you may just end up helping them. Sceptilite is a prime example. You not only could boost there SpA, but youll kill momentum, which offense needs desperately. It'll be important to have stuff to force the opponent to reveal their mega stone, so that basically once you start a sweep, it can't be interrupted by something like that, because, once again, if the sweep is cut short, it could easily lose you the entire match. Trying to stack stuff w/ common checks is going to be risky, because it's not always inherently clear what those checks are. This will hold back HO teams, too.
Stall isn't about psychic types, I have no idea what psychic type you'd even use effectively anyways. I'm only using one psychic type on my team and it handles all the top threats perfectly, the only problem I can look at straight away is Shadow tag. Gothitelles got a boost. Wobbuffet got a boost. Gengar is still horribly threatening to stall. And stall got nothing to help beat trapping, they can't run shed shell now. idk... trapping is already controversial and it's even more powerful in this metagame, so I don't see why we shouldn't ban it.
