If Teemo Strategist is hidden in a Bandle Tree controlled by a player, and that player has a unit on their opponent's battlefield, can Teemo be revealed and played to the opponent's battlefield in a later turn?

Ruling: No. Hidden units must be played to the battlefield they were hidden in.

Nuances:

• This restriction also prevents playing the hidden unit to your base
• The hidden unit can only be played to the specific battlefield where it was originally hidden
