Promise of Loyalty

four generic mana one white mana Sorcery

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!

If the vow counter is removed from the creature, it can attack as normal.
