What it does
I'm not familiar with "Gift of Chaos" as an official Magic: The Gathering keyword or ability. It's possible you're thinking of a specific card name, a homebrew/custom mechanic, or a misremembered keyword.
There is a "Gift" mechanic from Bloomburrow (2024), where certain spells let you give an opponent something (like a card, a Food token, or other benefit) when you cast them, in exchange for an additional effect for you. But "Gift of Chaos" specifically isn't a standard keyword I can confirm.
If you can tell me the exact card name or where you saw this term, I'd be glad to explain it accurately. I'd rather not invent rules text that could mislead you during a game—getting the interaction wrong in Commander can cost you a turn or a win.
