I am making a Kira, Great Glass-Spinner EDH deck and had a quick question. If I run a creature with an exploit ability (for example: Profaner of the Dead) where I have to sacrifice a creature to pull off the exploit, does the exploit get countered by Kira, or does it not matter because exploit says "sacrifice a creature" not "sacrifice target creature"?
If Kira does counter the exploit when I go to sacrifice the creature, does the exploit trigger still go off because I elected to sacrifice the creature but it didn't get sacrificed, or does it not work because the exploit was countered in the first place?
For those who would like context:
Kira's ability: Creatures you control have "Whenever this creature becomes the target of a spell or ability for the first time each turn, counter that spell or ability."
Exploit: When this creature enters the battlefield, you may sacrifice a creature.
