When a unit with Hidden is un-hidden on a later turn, must it be played to the same battlefield where it was hidden, or can it be played to a different battlefield or base?

Ruling: When a card is played from Hidden, it must be played to the same location where it was hidden. An additional restriction of "Here" is added to the card when played from Hidden.

Nuances:

• The battlefield itself is not a target, but the play location is restricted to where the card was hidden
• This restriction applies whether the hidden card is a unit or has other targeting requirements
