One ruling from Wizards of the Coast
- 1 September 2023An Aura put onto the battlefield this way doesn't target anything (so it could be attached to an opponent's permanent with hexproof, for example), but the Aura's enchant ability restricts what it can be attached to. If the Aura can't legally be attached to anything, you can't choose to put it onto the battlefield at all.
