Conjuro
Destruye el permanente objetivo que no sea tierra y todos los otros permanentes con el mismo nombre que ese permanente.
If the target permanent is an illegal target by the time Maelstrom Pulse tries to resolve, the spell won't resolve. You won't destroy any permanents at all. If the target is legal but not destroyed (most likely because it has indestructible), you do destroy other permanents with the same name.
