It's basically this:
Deoxys-S @ Focus Sash
Trait: Pressure
EVs: 4 HP / 252 Spd / 252 SAtk
Timid Nature (+Spd, -Atk)
- Stealth Rock
- Taunt
-
-
the last two slots can vary. I think it was ipl who used counter and mirror coat in the last slot (though I don't know if that was the person or now lol, it's 3:30 AM I dunno). Also choosing between special attacking options like Psychic, shadow Ball, Ice Beam, and Thunderbolt in the last slots is an option, to kill them off rather than messing around incapacitating them.
I like status on there too, but it's kind of a shame that a lot of common counters don't mind it much. Still, thunder Wave totally demolishes choice scarf leads and also faster scarfers like Azelf and Gengar that might want to switch in and kill you. I use Shadow Ball because my team is Azelf weak and you never know when it could come in handy lol.
I guess you could use superpower for Tyranitar too, since it's one of the few pokemon that can get deoxys killed on the first turn thanks to ss.
