My plan
1. Get a lot of entry hazards in (stealth rock, spikes, toxic spikes)
2. Use pokemon that are high in defense and no moves like: Quiver dance, calm mind, protect, subsitute
3. status affects are very important to wear them down
4. Recommened pokemon: Politoed, Ferrothorn, Blissey, Sableye, Whismiscott, Chansey, Audino and Smeargal
This is all thrown off the top of my head and from what I have seen. Its pretty much how to make a stall team that beats pokemon with out even having to use damaging moves. So...yeah.
