Shade The Night

Parry X (When you Parry, either destroy target piercer or place a parry counter on target piercer. Then, if there are at least ten piercers with parry counters on the battlefield, you gain control of all piercers with parry counters on them until end of turn.)

For every piercer you control, choose one:
• Destroy target piercer.
• Target player gains 1 life.
• Deal 1 damage to any target.
