Thanks for the help, I appreciate it.http://www.smogon.com/forums/threads/ubers-spl-replays-discussion-thread.3526174/
Check out donkey and Hack's teams for some cool ideas, they are probably the most solid stall teams that have been made / revealed edit: recently obviously
For a starting point I would go with Lugia+Magic Bounce, but you do still want Defog, something for Dark Arceus (Clef and I think Snatch Blissey), standard stall stuff like cleric support, etc. Ofc some kind of hazard goes without saying. Obviously some things need to be compressed to fit 6 mons (in donkey's team Unaware Clef also deals with any kind of GeoXern for example). Luckily Lugia more or less stops all physical attackers.
But anyway I don't really play stall so perhaps someone more familiar will give you a better answer
Also I was using a team in found in the RMT thread that was built around cm darkceus and m diancie. Pretty good stall team but kinda weak to set up sweepers (namely rock polish + sd groudon and m salamence).
