Promise of Loyalty

Each player puts a vow counter on a creature they control and sacrifices the rest. Each of those creatures can't attack you or planeswalkers you control for as long as it has a vow counter on it.

Cada jugador pone un contador de juramento sobre una criatura que controla y sacrifica el resto. Cada una de esas criaturas no puede atacarte a ti o a los planeswalkers que controlas mientras tenga un contador de juramento sobre ella.
