Khalni Gem

Artifact, 4 (4)

A fragment of ancient power lost in the heart of Ora Ondar.

Gatherer Card Rulings [Nov 2009]

• 10/1/2009: If you don't control any lands by the time Khalni Gem's triggered ability resolves, nothing happens. If you control just one, you'll have to return it to its owner's hand. Khalni Gem isn't affected in either case.
