Mindbreak trap from Zendikar reads:
Mindbreak trap

Instant, Trap
If an opponent cast three or more spells this turn, you may pay rather than pay Mindbreak Trap's mana cost.
Exile any number of target spells.
Now for example lets take Akroma, Angel of Fury which has the ability "Akroma, Angel of Fury can’t be countered."
So can I use Mindbreak trap on Akroma angel of fury? On one hand, by exiling Akroma from the stack I am basically countering the Akroma but it has the ability "Akroma, Angel of Fury can’t be countered."
On the other hand, Mindbreak trap doesnt specifically say "Counter target spell" it says to "Exile target spell" and Akroma doesnt say anything like "Akroma, Angel of Fury can’t be exiles."
So whats the deal, can I use mindbreak trap in this case or not?
