One ruling from Wizards of the Coast
- 16 April 2021This ability counts the total amount of life gained without considering any life you lost during that turn. For example, if you lost 3 life and gained 3 life earlier in the turn, you'll gain 2 more life from Blossoming Bogbeast and creatures you control will get +5/+5.
