One ruling from Wizards of the Coast
- 24 September 2021If you control more than one Unnatural Growth, each one applies independently. For example, if you control two copies of Unnatural Growth, a 2/2 Bear Cub becomes a 4/4 creature when the first ability resolves and then becomes an 8/8 creature when the second one resolves.
