MAGIC: THE GATHERING
|Type:||Land - Island Mountain|
: Add either or to your mana pool.
Counts as both islands and mountains and is affected by spells that affect either. If a spell destroys one of these land types, this card is destroyed; if a spell alters one of these land types, the other land type is unaffected.
The original "dual lands" are now highly sought-after collectables that see play in Eternal formats like Vintage and Commander. They are part of Magic's Reserved List, a pledge which Wizards of the Coast made not to reprint highly collectable cards like these.
