Delphox going first would probs ko opponent below one hit if not focus sash but if then hitmonlee uses knock off it would simply take its leftovers off and at the end of the turn delphox would steal hitmonlees held item if it still had one. plus delphox facing a life orb hitmonlee would most likely ko'd and this is RU rating so the Pokemon pool availabity is very limited in RU.
If magigican delphox has sitrus berry and opp used knock off first before delphox moving, sitrus berry would be gone obviously and if delphox still standing then it would steal opponents held item at the end of the turn.
because its held item was gone.
For a start this was hard to explain since you wanted it to be used for RU smogon rules. So in detail heres how it would really look.
Lets imagine this was Delphox's stats
Delphox @ Leftovers
EVs: 252 SpA / 26 Def / 232 Spe
IVs: 0 Atk
- Grass Knot
- Calm Mind
Cause its holding Leftovers and its fast it'll go first.. Opponent uses KNOCK OFFin this cause it'll be last because delphox is quicker. Below is an example of opponents stats:-
Hitmonlee (M) @ Focus Sash
EVs: 252 Atk / 4 SpD / 252 Spe
- Knock Off
- Blaze Kick
- Fake Out
- Rapid Spin
Because Delphox goes first, it'll most likely go for ko attack psybeam... hitmonlee has focus sash which will give it a chnce to hit bk...
Focus sash just been used and delphoxs magician doesn't get to work simply because it works at the end of a turn and taking on an item is very risky as you might get toxic orb flame orbs or choice items. If hitmonlee had life orb then psybeam would be beneficent and worth it but chances are someone would simply switch and sacrifice hitmonlee so it can rapid spin.
