Khalni Gem⁣ - Zendikar⁣ (Uncommon)⁣ [205]

Khalni Gem allows you to return two lands you control to your hand when it enters the battlefield, which can help reset your mana base for future plays. By tapping it, you can generate two mana of any one colour, making it useful in ramp strategies or multicoloured decks that need flexibility. However, the initial land return can set you back temporarily, so timing its deployment is crucial.
