2016-01-22
The enchanted creature can still be untapped by other spells and abilities.

Casting a spell for its surge cost doesn't change its mana cost or its mana value.

Containment Membrane keyword rules

Enchant Rule 702.5

Enchant 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 , “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.

Surge Rule 702.117

Surge is a static ability that functions while the spell with surge is on the stack. “Surge [cost]” means “You may pay [cost] rather than pay this spell’s mana cost as you cast this spell if you or one of your teammates has cast another spell this turn.” Casting a spell for its surge cost follows the rules for paying alternative costs in rules and –h.
