New Keyword: Gigantify

A new keyword is being added to the game - Gigantify! Play a card with this keyword to receive an 8 cost 8/8 copy of it added to your hand.

New Mechanic: Packs

Quote From Cora

As a heads up, Packs aren't so much a new mechanic as they are just a cycle of cards modeled after Elise the Trailblazer's Un'Goro pack. There are 3 different Pack spells, and each one will give you 5 random cards from a specific subset.

Quote From Blizzard

Dr. Boom’s been tinkering away in the basement of Whizbang’s Workshop, working on his own line of toys to prove that he is the greatest toymaker and inventor in Azeroth. He’s come up with something huge—gigantic, even—and he’s ready to share it with the world. Prepare to have your mind blown, these are Dr. Boom’s Incredible Inventions!

Dr. Boom’s Incredible Inventions, launching on May 14, consists of 38 new cards: 4 Legendary cards, 1 Epic card, 17 Rare cards, and 16 Common cards. Those cards can either be opened in Whizbang’s Workshop packs or purchased as a completed 72-card set.* Normal versions of the Mini-Set can be purchased for $14.99 or 2000 Gold. The all-Golden version of the Mini-Set can be purchased for $69.99 or 10,000 Gold, and includes a bonus Diamond Legendary card!

* Includes one copy of each Legendary card and two copies of each other card in the Mini-Set.

Master the Minis

Puppetmaster Dorian knows how to pull the strings on any minion. Each time you draw a minion, this master entertainer puts an extra 1-mana 1/1 version of it into your hand for a cheap burst of power. Puppetmaster Dorian is also the bonus Diamond card included in the Golden Mini-Set—talk about maximizing value!
