Sacrificing My Own Creature

[Desdas]

Hey if anyone ever casted the enchantment *stab wound* is my opponent able to just destroy the creature I casted it on? Like can he just destroy his own creature

[Trunksthemighty]

Not unless he has another card that says he can like  {Infernal Plunge}. You can't just sacrifice a creature for no reason

[Kareason]

He must have some outlet to sac it to. You can not just go "Well I will just sac it" without having something to sac it to. Examples of sac outlets would be {Nantuko Husk}, {Ashnod's Altar} or {Geth's Verdict}.
