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.

Each player, including you, must put a vow counter on a creature they control if able. They can't choose to opt out and sacrifice all of their creatures. The creature you put a vow counter on will remember its promise if another player gains control of it.
- WotCApr 16, 2021
If the vow counter is moved to another creature, it won't prevent the second creature from attacking normally.
- WotCApr 16, 2021
If the vow counter is removed from the creature, it can attack as normal.
