Gengar Lv.X vs Blaziken FB Lv.X

[BENDINGSPOONS1]

does the effect of Blaziken FB Lv.X's Jet shoot (plus 40 damage) go away if the opponent Devolves/Levels you down to Blaziken FB with Gengar Lv.X? In other words if your opponent levels your Blaziken FB Lv.X to Blaziken FB can the opponents Pokemon do plus 40 damage to Blaziken FB? Do all effects go away with devolving?

With Leveling down, you mean.

Yes, just as leveling up would clear attack effects, so would leveling down.
