misdirection being able to screw over force of will?

[jamestosetti]

I play on magic league and there is never the same ruling on say if an opponent cast force of will to counter your spell then yuo cast misdirection to redirect the force of will to the misdirection then  when force of will resolves there is no longer a legal target for the force of will?Does this work or does it not?

This will work.

It works because when choosing new targets for Misdirection, Misdirection itself is a legal target (a spell can't target itself, but it can make another spell target itself).  Misdirection resolves and redirects the Force of Will to it, but then Force of Will trys to resolve and sees that its target no longer exists (now the Misdirection), so it fizzles.
