EnchantEnchant is a static ability, written “Enchant [object or player].” The enchant ability restricts what an Aura spell can target and what an Aura can enchant.
For more information about Auras, see rule 303, “Enchantments.”
If an Aura has multiple instances of enchant, all of them apply. The Aura’s target must follow the restrictions from all the instances of enchant. The Aura can enchant only objects or players that match all of its enchant abilities.
Auras that can enchant a player can target and be attached to players. Such Auras can’t target permanents and can’t be attached to permanents. (CR 702.5) land you control
TapTo tap a permanent, turn it sideways from an upright position. Only untapped permanents can be tapped. (CR 701.26) enchanted land: Target blocking creature gets +1/+2 until end of turn.
ActivateTo activate an activated ability is to put it onto the stack and pay its costs, so that it will eventually resolve and have its effect. Only an object’s controller (or its owner, if it doesn’t have a controller) can activate its activated ability unless the object specifically says otherwise. A player may activate an ability if they have priority. See rule 602, “Activating Activated Abilities.” (CR 701.2) only if enchanted land is untapped.
