Forum:Pseudo-Flip Effects

If I attack the Pseudo-Flip Effects monster in face-down position with higher attack than the Pseudo-Flip Effects monster defense face-down position. If the Pseudo-Flip Effects monster is destroyed this way. Do it effect activate after that?

I just read that Pseudo-Flip Effects monster's effect can't be negate by a card negate filp effect monsters's effect because it doesn't a truely flip effect monster. and if that is so, means the Pseudo-Flip Effects monster are more advantage than the truely flip effect monster, right?

thank you
