Coveted Jewel - Commander: Modern Horizons 3 (Rare) [M3C-287]

Coveted Jewel is a six-mana artifact from the Modern Horizons 3 Commander set that allows you to draw three cards upon entering the battlefield. You can tap it for three mana of any one colour, but be cautious: if an opponent’s unblocked creature attacks you, they gain control of the Jewel and draw three cards as well. This card fits well in strategies that can protect it or utilise its mana generation effectively, but its control can shift if you're not vigilant.
