Defensive Formation

Enchantment, W (1)
Instead of the attacking player, you assign the combat damage of creatures attacking you.¹
"Your enemies will pound upon the door of your defenses, but only you shall have the key, and it is the key of life." -Song of All, canto 873
Illus. Greg Stapes

Crystal Keep Rulings Summaries

• You follow all the normal rules for damage assignment. For example, you can assign more damage to a blocking creature than its toughness, and if a creature has Trample (see Rule 502.9) you follow the Trample rules as appropriate. [Urza's FAQ 1998/10/05]
• Damage assignment choices from Trample (see Rule 502.9), Thorn Elemental, and other things which allow alternative damage assignments for attacking creatures are all made by you. [bethmo 1999/10/05]
