4 rulings from Wizards of the Coast
- 25 July 2025If two or more effects attempt to modify how many counters would be put onto a permanent you control, you choose the order to apply those effects, no matter who controls the sources of those effects.
- 25 July 2025If you control two Loading Zones, the number of counters put on a creature, Spacecraft, or Planet you control is four times the original number. Three Loading Zones multiplies the original number by eight, and so on.
- 25 July 2025If a creature, Spacecraft, or Planet you control would enter the battlefield with a number of counters on it, it enters with twice that many instead.
- 25 July 2025The Loading Zone is for immediate loading and unloading only. There is no stopping in the Loading Zone. (Especially not if it was warped.)
