How did Komala always use Last Resort via Sleep Talk?

Question

Komala used Sleep talk and always used Last resort, i'm wondering, how did Komala performed that? (this happened in Pokemon showdown btw) (i'm planning to use it for a Anti-Toxic team btw×2) and if you can answer this, could you include how it Outspeed my whole team, even my Deoxys Speed form and i'm not a Toxic Player, i'm just SUPER Confused and need a answer

Edit: the player answered me

Do you want to answer your own question now?

Ok, i will

Answer 1

What happened is that the Ability "Comatose" makes Komala always asleep, so it has just Sleep talk and Last resort, Sleep talk is the only move that unlocks Last resort and selects it because it has no other option but if you want to wall it, just use Ghost Type Pokemon

How did it out-speed your Deoxys-S though? Quick claw or trick room?

Maybe Choice Scarfed into Sleep Talk?
