Twincast

Intant
Copy target instant or sorcery spell. You may choose new targets for the copy.
I've just stumbled upon this card and am now considering its practical applications in Vintage. It seems to me that whilst it definitely has its flaws, it could have uses. As well as having obvious synergy with cards like Ancestral Recall and Time Walk, it serves as a response to an opposing Tinker or Time Walk, it can serve to counter a counter, and it seems like it could (mana permitting) work quite well with Snapcaster Mage, i.e. Ancestral Recall, flashback with Snapcaster, Twincast the flashbacked Ancestral Recall. Also, when it's not playable/useful, it pitches to Force of Will.

Obviously, perhaps the biggest problem with this card is that it costs

to play, meaning that if you're copying your own spell it will almost definitely have to be a very low cmc spell, and if you're copying a counter you will very likely have had to have spent mana playing another spell previously, making it harder to play Twincast.
So, does this card have any place in Vintage at all? Perhaps as a one or two of in a blue control deck?
Thoughts? Opinions?
