Darksteel Garrison

Artifact - Fortification, 2 (2)
Fortified land is indestructible.

Whenever fortified land becomes tapped, target creature gets +1/+1 until end of turn.

Fortify {3} ({3}: Attach to target land you control. Fortify only as a sorcery. This card enters the battlefield unattached and stays on the battlefield if the land leaves.)¹

Gatherer Card Rulings [Nov 2009]

• 5/1/2007: Fortification is to lands what Equipment is to creatures.  Except for the difference regarding what kind of permanent it can affect, Fortifications and Equipment follow the same rules.
• 5/1/2007: If Darksteel Garrison and the fortified land would be destroyed at the same time, only Darksteel Garrison is destroyed.
• 5/1/2007: The second ability triggers whenever the fortified land becomes tapped, not just when it's tapped for mana.
• 5/1/2007: The triggered ability is mandatory. If you don't have a creature to target, you must target another player's creature, if possible.
