>>22085912e speed outspeeds it anyway, but lowers your defense and attacks apparently and assuming the opponent will likely survive itll kill you in one hit
thats not even creative, its just dumb
here's a speed deoxys set
Stealth Rock
Taunt
Spikes
Knock Off / Magic Coat
Here's Deoxys Defence
Stealth Rock
Taunt
Spikes
Thunder Wave
See a pattern?
Guess which is used more.
.. and here's Deoxys Attack
Psycho Boost
Low Kick / Superpower
Ice Beam / Knock Off
Extreme Speed / Hidden Power Fire
Deoxys-Attack needs extreme speed because it's frail and needs to kill quick, you're basically telling it to not kill anything and just die.
