Before the Mending

Cast Before the Mending only if you control three or more planeswalkers.
You get an emblem with "Planeswalkers you control gain indestructible, protection from non-planeswalkers and can't be exiled or sacrificed. You may spend mana in place of loyalty to activate the loyalty abilities of planeswalkers you control. Each planeswalker you control can use loyalty abilities that would reduce loyalty any number of times each turn."
