If I hide Sprite Call, can I place the token on another battlefield or in base when I cast the spell?

Ruling: When you play a hidden Sprite Call, you must place the sprite token on the same battlefield where the spell was hidden. You cannot choose a different battlefield or your base.

Nuances:

• Hidden cards have an additional restriction requiring you to choose the hidden location when determining where to play the card itself
• This restriction applies even though Sprite Call doesn't target - it still chooses where to play the unit
• You can alternatively play Sprite Call from your hand by paying its energy cost, which would allow normal placement choices
