Disciple of bolas

[Deathstorm]

So when {disciple of bolas} enters the battlefield can I sacrifice a creature my opponent controls it doesn't specify on the card

[Willthomjr]

You can sacrifice only creatures you control.


No

[Poof]

Yea it wouldn't be a sacrifice if u could kill off their creatures. 

[Deathstorm]

I thought so but normally they specify especially on a core set
