can you cast a counterspell without a target in magic?
can you cast a counterspell without a target in magic?
no. Anytime a card say it does X to target, then you must have a legal target to cast the spell.
In this case it's says counter target spell, therefore, there has to be a target spell or you can't cast it.
On a side note, some cards are worded so it's spell does X to up to Y target....
In this case because the spell has an up to number but no minimum you can cast it naming 0 as the number of targets for Y.
