Ladder wins? You should read everything, I used it in tour battles as well.I have to disagree with some of what you said. First, ladder wins are not the most concrete evidence for the viability of stall. Secondly, of course you beat some good players. You win with stall because people don't think anyone will use it when building their teams. If they expected it, there are many good Pokemon they could just add as good stallbreaker and pressure the living daylight out of stall. Third, it says something when you have to devote 2 Pokemon on a team for seeing what move Exeggutor will use, and if it is Yache Berry, Avalugg is screwed. There are so many different sets that Exeggutor can use to get around a check, especially with Sleep Powder
I have to devote two mons to see its move? Audino is stall's main pivot, it does that alone; no need for an extra poke to scout. If it's yache berry, it can't touch the team because it doesn't have enough power, no need to even bring avalugg then. Sleep powder can't sleep gourgeist and the most common set with sleep powder can't touch it either. Please read my post more carefully and then see some battles of stall vs teams with eggy; then talk to me about it and I'll be happy to procede this conversation.
And last but not least, I can see your argument of "people don't expect it" for stuff like offensive gourgeist, physical eggy etc. I can not expect it for an entire playstyle. If you don't "expect" an entire playstyle, that's not good planning...
