This isn't true, Deo-S only needs 16 Atk EVs to OHKO Ttar:The Attack EVs enable Deoxys-S to KO max HP Tyranitar with Superpower.
16 Atk Life Orb Deoxys-S Superpower vs. 248 HP / 252+ Def Tyranitar: 296-354 (73.4 - 87.8%) -- 6.3% chance to OHKO after Stealth RockJust a really small nitpick, I know this is 'done' and all but..
This isn't true, Deo-S only needs 16 Atk EVs to OHKO Ttar:
16 Atk Life Orb Deoxys-S Superpower vs. 252 HP / 0 Def Tyranitar: 406-478 (100.4 - 118.3%) -- guaranteed OHKO
Therefore, a spread of 16 Atk / 252 SpA / 240 Naive is the most ideal.
See, SR on Deo-S just is alright. It can't pivot into anything and is generally unable reset the hazard, whereas something like Lando can. Also, giving up coverage sucks. SR is good, but Knock Off is insanely useful and definitively deserves the main slash. I've already conversed with other people about this.I think SR should be the first slash on the RK set's final slot. Knock Off is nice to mess with Aegis and Chansey, but Deo-S's ability to set up SR shouldn't be underestimated, especially since it can threaten out a variety of fast offensive mons. There are many other mons that make better use of Knock Off, but none can give you that utility of a blindingly fast SR combined with amazing revenging potential. It's Deo-S's best set and easily deserves the first slash in my book.
Substitute is cool on any attacker, but its not a good option on Deo-S because first it is affected by all forms of residual damage + LO recoil so Substitute wears it down even faster which isn't great, second it is easiely forced out due to the Stat drops of its main attacking moves Psycho Boost and Super Power and finally your substitutes can be broken by virtually any OU Pokemon thanks to its poor typing and mediocre bulk. Honestly unless you can reliably set-up a substitute on some prominent OU threats without the need of forcing it out it is always a shaky option.Would Substitute be a possibly viable option on the Life Orb Revenge Killer set? I've been seeing a lot of Bisharp recently, so I decided to put Substitute over Knock Off and it works well for me. It allows Deoxys-S to avoid the OHKO from Sucker Punch and KO back with Superpower. It also saves it from Pursuit mind games. Maybe it's not worth it, but I think it has a use.
