- 27 January 2026The five colors are white, blue, black, red, and green. Colorless is not a color.
- 27 January 2026Mondo Gecko's first ability causes it to become only the chosen color. It will no longer be the color or colors it was previously. (It will still have hexproof from any other colors chosen that turn.)
