- 8 November 2024The value of X is determined only once, as Ashroot Animist's last ability resolves. The value of the bonus won't change later in the turn if Ashroot Animist's power changes.
- 8 November 2024If Ashroot Animist leaves the battlefield before its last ability resolves, use its power as it last existed on the battlefield to determine the value of X.
