How did Pachirisu outspeed a Rotom Mow?

I’ve been watching this video about Wolfe reacting to that Pachirisu and Garchomp that won a worlds vgc tournament. In the final turns, Garchomp was at -1 speed and attack so it should be slower than Rotom, yet Pachirisu went first and hit it with a super fang before Garchomp finished it of with a dragon claw. So, how did Pachirisu, of all things, manage to go first?

I was going to have a very elaborate answer but someone reloaded my page and I’m not writing the whole shebang again. <:P

I assume you meanthis match. :P

Garchomp is Jolly (Level 50) with -1 Speed, has a perfect Speed IV, and 252 Speed EVs. This makes itsRaw Speed 112. Pachirisu is Impish and needs 52 Speed EVs to tie Garchomp’s Raw Speed (and likely has some Speed investment due to its role). It is likely that Rotom is built Defensively, especially die to having max HP, so its spread is not far off from252 HP / 252 Def / 4 SpD,which checks out as very possible in calculation:

252 Atk Garchomp Dragon Claw vs. 252 HP / 252+ Def Rotom-Mow on a critical hit: 72-85 (45.8 - 54.1%) – 50% chance to OHKO

Rotom’s Raw Speed would then be around 106 give or take 4. 110 is slower than 112, so Garchomp and Pachirisu’s better Speed stats warrant them enough Speed investment tonarrowlyout-speed Rotom-Mow, even with Garchomp at -1 Speed.:P

Hope I Helped!

Pachirisu has a higher speed stat then rotom.Rotom now has 86 speed. Pachirisu has 95 speed. Simple.
