Does anyone know if there's anything important for Vikavolt to outspeed with 0 investment? I'm trying a Vikavolt set out, and I'm considering running absolute minimum speed (0 IVs, 0 EVs, hindering nature) so that I can use Vikavolt to respond to Trick Room teams.
At level 100:
With 31 IVs/0 EVs and neutral nature, it has 122 speed.
With 0 IVs/0 EVs and hindering nature, it has 81 speed.
Are there any important mons in the middle of this range that Vik needs to outspeed? Because if not, I'll definitely go absolute min speed to give my team a Trick Room answer.
EDIT: So I did the math, and since regular Vikavolt has base speed 43, it has an
effective base speed of 22.5 when running min speed. This means that min-speed Vik loses the ability to outspeed uninvested mons with base speed of 23-42 and loses the ability to speed tie against other base 43s. In exchange, it can outslow min-speed mons with a base speed of 65-44, and slow-tie against min-speed base 43s.
Only counting the Alola dex (i.e. no pokebank mons), these are the pokemon whom min-speed Vikavolt will lose the ability to outspeed:
Gigalith, Shiinotic, Wishiwashi, Reuniclus, Bastiodon, Slowking, Slowbro, Snorlax, Sudowoodo, Parasect, Carracosta, Palossand, Mudsdale,
Toxapex, Corsola, Drampa, Turtonator, Gastrodon,
Dhelmise,
Golisopod, Probopass, Rhyperior, Ariados, Rhydon, and
Araquanid. (It also no longer speed ties with Guzzlord, Crabominable, or other Vikavolts who share a base speed of 43.)
*Bolded mons have a usage of 3% or higher according to the November usage stats, which means they are at or near OU-level usage (3.41%) and are more likely to be encountered.
In exchange for being outsped by these mons under normal circumstances, min-speed Vikavolt can now out-slow the following min-speed mons under Trick Room:
Lurantis, Gumshoos, Conkeldurr,
Alolan-Marowak,
Alolan-Exeggutor, Alolan-Golem, Wigglytuff,
Carbink, Eelektross, Sableye, Hariyama, Piloswine, Azumarill, Chansey, Alolan-Muk, Relicanth, Blissey, Machamp,
Magearna,
Porygon2, and
Oranguru. (It is also able to slow-tie against min-speed
Crabominable, Guzzlord, and Vikavolt.)
*Bolded mons are the ones I can recall facing often in Trick Room teams. (This is not an objective measurement.)
There are important mons either way, so it's a matter of preference. You can also go somewhere in between 0 IVs/hindering and 31 IVs/neutral to customize which mons you lose/gain the ability to outspeed. (For example, by dropping to 29 IVs and running a neutral nature, Vikavolt out-slows Magearna under Trick Room and drops to a speed tie vs Araquanid, without losing the ability to outspeed uninvested base 41s and lower.)
