6 rulings from Wizards of the Coast
- 7 June 2024If the creature with exploit isn't on the battlefield as the exploit ability resolves, you won't get any bonus from the creature with exploit, even if you sacrifice a creature. Because the creature with exploit isn't on the battlefield, its other triggered ability won't trigger.
- 7 June 2024You choose whether to sacrifice a creature and which creature to sacrifice as the exploit ability resolves.
- 7 June 2024A creature with exploit "exploits a creature" when the controller of the exploit ability sacrifices a creature as that ability resolves.
- 7 June 2024You can target an artifact or creature you already control (including Infernal Captor) with Infernal Captor's last ability just to untap that permanent and give it haste.
- 7 June 2024You can sacrifice the creature with exploit if it's still on the battlefield. This will cause its other ability to trigger.
- 7 June 2024You can't sacrifice more than one creature to any one exploit ability.
