(If you were thinking that Psyshock bypasses Light Screen, it actually  doesn't. Honestly, I thought it did too! Until deadfox researched it for  me and noticed that it didn't... despite hitting on the Defense. Odd to  me!)
(But that sucks because that means Machoke won't woke up on the first  action lol. I wanted "If a sleeping Pokemon is hit with a single attack  that causes sixteen (16) or more damage, it will wake up one action  sooner." to activate. :( )
