Prices from Scryfall, which tracks the TCGplayer and Cardmarket markets. They move daily and are a guide rather than a quote. Search TCGplayer for Caves of Koilos. It runs a name search across every version, which covers the printings TCGplayer publishes no direct link to.
Aggregated from Commander games tracked in TurnZero HQ. Every figure counts decks and games only. No individual deck list, player or playgroup is identified. Win rates are withheld below 5 completed games, where the sample is too small to mean anything.
