One ruling from Wizards of the Coast
- 29 September 2017The entering creature's toughness is determined as the ability of Verdant Sun's Avatar resolves. If that creature has left the battlefield, use its toughness as it last existed on the battlefield. If the creature's toughness was less than 0, your life total won't change.
