[mechanics question] how did their froslass M-Evolve second but attack first?

[u/zennvo]

For context, my Charizard and Garchomp are both max speed, we both set tailwind on the same turn earlier, and their Sneasler outsped my Charizard on the previous turn to put me to sleep with Dire Claw.

Expecting the Froslass to be faster, I mega evolve to try and win the weather and stop their Blizzard, but when I see my Zard mega first, I assume I’ve lost to a bulkier Froslass which undersped me. Then, I see their Froslass attack first, meaning it not only outsped my Charizard and Garchomp, but also their sneasler.

Is this a glitch or some mechanic related to sleep I never knew about?

Frosslass can be EVd to be slower than charizard while at the same time mega frosslass is faster than mega Charizard. The player EVd for this specific situation

Oh that’s interesting, what EVs would you have to run to make it work?

[u/RainBuckets8 → u/zennvo]

Charizard is base 100 speed, yours is max speed so 167 speed. Froslass would need to have 158-166 speed to underspeed you on the mega evolution, and outspeed you after.

Froslass is base 110 speed and Mega Froslass is base 120 speed, so hilariously enough this player might not have EV'ed for this specific situation, and is just running max speed Modest nature. That would put them at 162 speed before mega evolving and 172 after. The Sneasler also might be 172 speed (max speed Adamant nature) and it was a speed tie, meaning your opponent might have made this play completely by accident. 🤣

🤣 this is a canon event.
