"Log 2.2.119: Kiln, known for its blazing forges and ancient lava seeps. The footing may be treacherous, but the metallurgy is grand!"

Edge of Eternities

Ravnica: Clue Edition

As Sacred Foundry enters the battlefield, you may pay 2 life. If you don't, it enters the battlefield tapped.

Ravnica Remastered

({T}: Add {R} or {W}.)
As Sacred Foundry enters the battlefield, you may pay 2 life. If you don't, it enters the battlefield tapped.

If an effect puts this land onto the battlefield tapped, you may pay 2 life, but it still enters tapped.

Unlike most dual lands, this land has two basic land types. It's not basic, so cards such as District Guide can't find it, but it does have the appropriate land types for effects such as that of Drowned Catacomb (from the Ixalan set).
