Heroes for Hire III

This event ran during April 2017. Black Bolt, Medusa, Crystal, and Lockjaw were introduced in tandem with this event.

Rules

 * Clearing the event rewards you with a new Tsum: Lockjaw.
 * Clear missions to earn Medals!
 * Each mission has a number of medals you will earn by completing that mission and the card itself will have a total number of medals you have to get to complete the card.
 * The number of medals you get for a mission varies both by how difficult the missions is and the 'Rarity' of the mission. "Super rare" missions are worth more than "rare" missions.
 * Collect Medals to fight Battles! Win for rewards!
 * Once you have gotten enough medals to complete a card you will have one final mission: a battle against a hero where you will have to defeat a certain number of that Hero's Tsums. There battles are similar to some other battles where there will be several smaller Tsums you are battling at once that will be replaced as you defeat them.
 * After you win the final battle you will get the prize for that card and the card will be replaced with a new and more difficult card (with progressively better prizes). There are a total of 21 cards to complete during the event!
