If a hidden card is played on a battlefield with a unit, and that unit dies the same turn (due to combat from a Charm effect), what happens to the hidden card?

Ruling: The hidden card goes to the trash. Hidden cards can never be played the same turn they are hidden.

Sequence:

• Player hides a card on a battlefield with their unit
• Opponent uses Charm to force their unit to that battlefield
• Both units die in combat
• The hidden card goes to trash without being played

Nuances:

• This applies regardless of why the unit dies on the same turn the card was hidden
