Keeping with the theme of KotFT, I chose to make a hero card for warlock. This card is designed for a more control style warlock who would need to get the most value out of their spells. This card also has a place in discard (assuming you don't discard this card) variants, allowing you to more quickly activate Lakkari Sacrifice. The effect can work against you if you use cards like Hellfire, Felfire Potion and Blastcrystal Potion by doubling the negative consequences of those cards. Note that this effect does not extend to spells added to your deck or hand after changing your hero.

Cards that already have the cast it again effect will now cast an additional time. For example, if Defile would normally be cast twice, it would be cast a third time.

To accompany this card is a powerful hero power that compliments the card's battlecry effect. To use this hero power most effectively, players should consider using it at the beginning of their turn, casting a spell, then using it again. Note that the hero power does not trigger each time a spell of the same name is cast twice. The hero power summons an Abyssal.

With Knights of the Frozen Throne recently launching, I wanted to design a Shaman hero card for this challenge. Based on how it is played, it can either win you the game or bring you back from behind.

The Hero Power provided by this card allows the player to continually summon Jade Golems to keep a presence on the board. While not nearly as overwhelming as Jade Idol with Gadgetzan Auctioneer, it gives the class an effective tool for the late game that can make it viable in control or fatigue matchups.
