Sorry if this has been asked before, but my friend says that in Arena rules "sacrifice a creature" means you can sacrifice creatures you don't control (like an opponent's) as well as ones you do, unlike the tabletop game, since the wording doesn't specify your creature specifically. I can't find a copy of the Arena rules to verify this and I don't have any cards with sacrifice a creature in Arena yet to check that way so I thought I would ask here cause it seems kinda OP if so?
