The analysis doesn't mention anywhere this set,and i use it massively.Let's say it's the epitome of a defensive poke.Well,there it is:
Scizor@Leftovers
Technician
252 hp/252 def/6atk
Iron Defense
X-Scissor
Metal Claw
Roost
What this set does achieve?Well,it stops any non-SD physical attacking poke,and it's probably the best 1X1 poke(the last poke in both teams)
Iron Defense makes it real bulky at physical attacks,while Roost is there for recovery.Note that he's immune to Toxic,which pokes with 50% recovery move really hate.
Then X-Scissor is there for STAB.And Metal Claw.Metal Claw?
50 BP isn't too weak?And it's a steel type attack!!!Well,let me say one thing:Technician.
Technician boosts it to a good 75 BP plus STAB,with a 10% chance of raise attack.One more thing:64 PP!!!!That's probably it's one of the best last pokes 1X1 stall thing.Stell type almost doesn't matter.
Pros:it counters a HUGE list of physical attackind based pokes who can't raise the attack.It can take a surf or two from bulky waters too.Paired well with either Dugtrio or Blissey
Cons::Run like ther's no tomorrow of fire types.They laughs at the set.Stay away from powerful special sweepers too,and phazers.You can't compete with Swords Dance pokes too.But,well,you have another 5 pokes in your team to take care of that.
