It's not nessecarily uncounterable, also gives the mage the option to just reapply it's own buffs if they look through the "Bluff".

Aka if you use Snatch spell in the open, it's pretty much 3 wasted M. that is pretty tactical. Most mages also have alternative means to attack and even destiny mages can go the "Yeah fuck that, I just charge my laser!"

We could add the "If knocked down Snatch Spell is negetaed" suffix though. So even full mages have a full counter to this.

Edit:
Or give them a third snatch skill that works against those exclusively *shrug*
