ok here is the jiff

lets say i have mun 3 drop blade (mun) and my opponent has 3 drop invisible woman (mvl) in the hidden. i attack invisible woman with blade (its declared legal) i opt to use blades effect to move to the visible but at this time my opponent plays force field projection removing me from the attack.

question is does blade's effect resolve to where invisivble woman is mover visible or does it just fizzles out since the attack was removed from force field projection??

Blade can attack hidden characters.

Whenever Blade attacks a character, you may have that character's controller move it to his other area.

--------------------------------------------------------------------

Cost: 3 Force Field Projection
To play, exhaust an Invisible Woman you control.
Remove target defender you control and all attackers from this attack.

Once the attack is seen as legal, and the attacker exhausts, Blade's effect goes on the chain. Once on the chain, nothing in the above scenario will stop Invisible Woman from not moving to the visible area.

There are two wordings in your post that I want to follow up on.
At this point in the scenario, you shouldn't have made any sort of choice with Blade yet. His effect goes on the chain regardless of whether or not you actually plan to use it. You should only be deciding the "you may" choice as the effect resolves.
There is no such thing as removing an attack. Unless one player outright loses the game, every attack continues until both players have passed while the chain is empty, and every attack goes through a conclusion. FFP removes characters from the attack, it doesn't end the attack early.

As for Blade's effect, there's no reason it would fail to shunt her visible once it's on the chain. FFP doesn't say that it negates anything, so it doesn't. Blade's effect doesn't target anyone, so there can't be any legality issues. And his effect has no "if" conditions, so there are no checks you could possibly fail.

and a happy holidays to you, HeroComplex!

HC is my favoritest, slapping people with VS Knowledge since 2003! LoL I just made up that year btw. Anyway, yeah always conclude your attacks. Don't assume because attackers or defenders got removed that the attack is over. And please. If you love this game, Read the CRD all the way through at least once! Just once is all I ask. :-D
