Reverence Trap

If five or more creatures attacked you this turn, you may pay 4 life and {1}{w}{w} rather than pay Reverence Trap's mana cost.
All creatures lose all abilities and have base power and toughness 1/1 until end of turn.
Whenever the Mirran resistance gains ground, Elesh Norn takes it upon herself to ambush a raiding party. No shock is needed to demonstrate to them the glory of Phyrexia. Only awe.
