Can instant-speed sacrifice effects be used on creatures that enter the battlefield with 0 toughness?
Asked by Psychonautical 4 years ago
My opponent has two Planeswalkers on their battlefield. I have a Vampire Hexmage on my side, and I cast Cauldron Haze to give it Persist before sacrificing it to remove all Loyalty counters from one of the opposing Planeswalkers.
Upon returning the the battlefield via Persist, the 2/1 Vampire Hexmage will then have a -1/-1 counter on it, causing it to immediately die.
Am I able to use her sacrifice effect before she dies to kill the other Planeswalker? Or any other instant-speed effect for that matter?
