How quickly everything can fall apart. Without warning, Kaladesh authorities storm the village. Before you know it, your father lies dead, the village burns, and Baral has framed you for the destruction. His lieutenant advances to take you prisoner.
The opposing deck's theme is apparent from its inclusion of no fewer than ten Arrest variants, along with two Banisher Priests.
It is possible for Chandra to win via creature combat, but the simplest path to victory is to just burn the opposition out with your noncreature spells, which Baral's Lieutenant has no way of interacting with, unlike Chandra's creatures.
For this mission, Chandra now has two Chandra's Ignition and an Arcane Teachings. With the many Arrest effects Baral's Lieutenant has, Arcane Teachings isn't very reliable, since the enchanted creature would just get neutralized by an Arrest. On the other hand, Chandra's Ignition is useful even on a creature that has been Arrested; it can still deal damage despite not being able to attack or activate its abilities.
