A widely possible sweeper strategy!!!

[HoundoomOfTheDarkness]

Recipe... for destruction!

1. Get any sweeping Pokemon. I recommend a +Spd, -(s)Def nature.
2. Add EVs. Max out Spd and your (sp)Attack stat.
3. For physical, teach Swords Dance. For Special, make sure it has Tail Glow or Nasty Plot.
4. Give it a Focus Sash.

Finale! In battle, stat boost once. Your survival is guaranteed due to the focus sash. Until you get KO'd, your stat is doubled. This is much better than choice band, except it uses a move slot and Sandstorm utterly destroys it. Sandstorm eats Focus Sash users for breakfast and has seconds for lunch.

This strategy was figured out far before you did.

Spikes, Stealth Rock and weather makes it fail.

Why lower defence when you can lower the attack you don't use

And yeah it's an already thought up strat, my Houndoom uses it :P

For how common TTar is, it makes this strategy fail...and without a spinner, SR eats you...and nearly every team has that, rendering this strategy useless...
