>>44441274The main thing is, as
>>44441460 mentioned, stall tend not to have actual wincons or really, really slow ones (best example that comes to mind is sableye CM mono attack) they're usually built to just not lose until the win happens.
"Offensive mons" can find a room in stall team, things like pic related, dugtrio and goth in oras were at some point stall staples but they're usually silver bullet against things OU simply can't stall out or run very specialized defensive sets in an attempt to stall, like moltres does with sub+roost+pressure
