2 rulings from Wizards of the Coast
- 25 July 2025If Possibility Technician leaves the battlefield, the effect allowing you to play the exiled cards if you control a Kavu continues to apply, even during later turns.
- 25 July 2025You pay all costs and follow all timing rules for cards played with the permission granted by Possibility Technician’s first ability. For example, if an exiled card is a land card, you may play it only during your main phase while the stack is empty.
