Focus sash is a must-have item
jammie jammie earthquake @ Deck Night.
I wanted to keep this a secret, but I´m a guy of the truth and I don´t like witholding information.
Anyway, here it goes.
Bastiodon @ Focus Sash (this is a must-have item)
Protect (you don´t want to be quick attacked or anyting)
Metal Burst (...)
That is the must have part-set. Other possibilities are:
Block / Stealth Rock
Rest / Roar
Nature: Sassy
Ability: Sturdy
EV: 252 Hit Points 252 Special Defense 4 doesn´t matter
-speed nature is a given as well as 252 EV HP.
The rest is all just preference. So I like this:
Bastiodon @ focus sash
Sassy @ 252 HP + 252 SD + 4 wasted
Protect
Metal Burst
Rest
Stealth Rock
Protect + Metal Burst is for the revanche KO.
Anything that has 300 attack and earthquake will OHKO it.
That is, let it leave 1 HP.
Metal Burst 1.5x 300 (if low IV or whatever) = 450 HP damage.
Protect is to check if someone really attacks or not.
If they do a normal typed attack, your focus sash is useless.
Taunt isn´t a very good idea, because the moment you are taunting,
the opponent can OHKO you with earthquake or leave you helplessly with 1 HP.
Put this guy in a (healing) wish team and you can maybe pull it off twice or at least send him in again to be used as a wall.
It is not what you say an easy to use Pokémon and a bit high mind-gaming, but that´s the fun of him.
Counters:
Trick Room really messes it up of course.
If it becomes popular it will become a pseudohazer.
Feint is pretty deadly as well.
Spikes, allthough they do little damage mess up focus sash as well.
Wobbuffet theory: if you don´t attack it, it can´t do anything.
Hail
Conclusion:
It is probably a bit of a novelty, but it can have it´s surprises. If you decent in a good team hey maybe able to swich in at times to to other jobs as well.
Even when used professionaly it has earthquakes for breakfast!
