Can you tell me the rulings for Pia Nalaar?
user
0. Once a creature has blocked an attacking creature, activating Pia Nalaar's last ability won't cause the attacking creature to become unblocked.
1. The “legend rule” cares about legendary permanents with the exact same English name. The Kaladesh™ card Pia Nalaar and the Magic Origins™ card Pia and Kiran Nalaar have different names, so you can control both at the same time.
