Rature magique 064/302

Change the text of the targeted spell or permanent, replacing all instances of one basic land type with another. (For example, you can change "Traverse the Marshes (This creature is unblockable as long as the defending player controls at least one Swamp.)" to "Traverse the Plains (This creature is unblockable as long as the defending player controls at least one Plains.)." This effect lasts indefinitely.)
