Whenever a land an opponent controls is tapped for mana, tap all lands that player controls that could produce any type of mana that land could produce.
Creatures and lands you control have shroud. (They can't be the targets of spells or abilities.)
When a creature you control attacks, sacrifice this enchantment.
Enchant land
When enchanted land becomes tapped, destroy it and this Aura deals 1 damage to that land's controller. That player attaches this Aura to a land of their choice.
