5 rulings from Wizards of the Coast
- 2 February 2024When an effect suspects a creature, it becomes suspected. It gains menace and "This creature can't block" for as long as it's suspected. It stays suspected until it leaves the battlefield or another effect causes it to no longer be suspected.
- 2 February 2024Being suspected isn't a copiable value. If a permanent becomes a copy of a suspected creature, it won't be suspected.
- 2 February 2024There's no limit to the number of creatures that can be suspected simultaneously. Suspecting a new creature doesn't cause other creatures to stop being suspected.
- 2 February 2024If a creature is already suspected, suspecting it again won't have any effect.
- 2 February 2024If a suspected creature loses all abilities, it will lose menace and "This creature can't block", but it won't stop being suspected.
