As always, stay tuned for more information regarding Hearthstone and general gaming news! If, for example, you have nine-mana and you have a 3-cost minion with Echo, you can play that minion three times in the same turn.
Players can draw on an arsenal of new tricks, including the eerie new Echo keyword.
Oh, and I'm pretty sure those Hearthstone guys in the video are actually perfectly OK, so you can stop worrying about them and have a look at the first of the new cards down below.
More cards will be revealed starting with the 26th of March, when we will probably also get a more in-depth analysis of the new cards and abilities. Aside from winning new cards, players will be able to round out their collections by purchasing new card packs or disenchanting some of their existing cards to craft the ones they're missing.
The Witchwood will be released sometime in April. The first is Echo, which allows you to play the same card multiple times in the one turn, as long as you have the Mana to pay for it. The new Monster Hunt mode will work similarly to the Koboids and Catacombs' Dungeon Run, as you'll need to take on a string of encounters, before eventually coming face to face with a boss. However, if your deck only contains odd-Cost cards, it will upgrade your Hero Power. "They can not attack heroes until the turn after they enter play, however".
Second, the devs reveal neutral Legendary minion, Genn Greymane, whose Battlecry reduces the cost of the player's Hero Power to one mana, provided all the cards in their deck and hand are even-numbered-cost cards.
In The Witchwood's exhilarating single-player mode, Monster Hunt, Gilneas' greatest heroes are called to cleanse the forest of this darkness. Rush, much like Charge, lets a minion attack immediately, but only against other minions.
