- 24 September 2021Gorex's first ability can't reduce its cost below {B}{B}. You can exile any number of creature cards from your graveyard, even if they won't reduce Gorex's cost any further.
- 24 September 2021Include any additional costs to cast Gorex before applying its own cost reduction. For example, if Gorex is your commander and an additional cost of {6} applies from the "commander tax," you may cast Gorex by exiling four creature cards from your graveyard and paying {4}{B}{B}.
