A huge update is coming for Hearthstone's June season of the Twist format bringing in plenty of new heroes, hero powers, and pre-constructed decks to the format.

The most interesting part of this is the monetization aspect of the format. In order to play with a specific hero in Twist, you'll need to unlock it by owning the corresponding legendary card. Luckily, 4 of these heroes are available in the core set so they will be free to play, and another 2 were free in the past (C'Thun and Kael'thas Sunstrider) or easily available by purchasing a single Old Gods or Outland pack. For the remaining 13 though, you'll need to find them in packs or craft them with dust if you want to make use of them.

Blizzard has not yet revealed all the details on the heroes and what their hero powers will be, or how their decks are constructed, but we'll see more on that closer to the launch. Read on for Blizzard's post taken from the Patch 29.4.0 notes.

Quote From Blizzard

Twist is back with a huge, all-new season in June: Whizbang’s Heroes! In Whizbang’s Heroes, choose from exciting new Heroes, each with their own pre-constructed deck, Hero Power, and unique passive effect.

Each Hero is unlocked if you have their corresponding Legendary card (the first-appearance card with the same name as the Hero—except Illidan, who is unlocked by Metamorphosis in Core).

Whizbang’s Heroes will launch with 19 Hero options:

  • Illidan Stormrage*
  • Al’Akir the Windlord*
  • Arch-Villain Rafaam*
  • Leeroy Jenkins*
  • Kael’Thas Sunstrider**
  • C’Thun**
  • Nozdormu
  • The Lich King
  • Xyrella
  • Patches the Pirate
  • Sir Finley Mrrgglton
  • King Krush
  • Forest Warden Omu
  • Dr. Boom
  • Zul’jin
  • N’Zoth, the Corruptor
  • Brann Bronzebeard
  • Guff Runetotem
  • Arfus

Keep an eye out for more details closer to the start of the June Twist season!

*These heroes are unlocked by cards in Core, so they will be automatically unlocked for all players at the start of the season.

**These two cards were free login rewards for older expansions. If not already unlocked, C’Thun is automatically unlocked by having a Whispers of the Old Gods pack and going to the pack opening screen and Kael’thas is automatically unlocked by having an Ashes of Outland pack and going to the pack opening screen.
