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.
And so was born the Fantastic Four! And from that moment on, the world would never again be the same!

- 2021-04-16Each 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.
- 2021-04-16If the vow counter is removed from the creature, it can attack as normal.
- 2021-04-16If the vow counter is moved to another creature, it won't prevent the second creature from attacking normally.
