Blizzard has released their debut World of Warcraft expansion for the Year of the Raven, called The Witchwood. The expansion will include 135 cards, as well as a new single-player game and is scheduled to be released in April.

The team revealed six cards on Tuesday and more reveal events are planned for to be revealed on the livestream of March 26 and gradually before the release. The six cards that were revealed today provide glimpses of this expansion's flavors, which include two brand new words. The one is Echo, that allows you to play the same game multiple times in one turn, so long as you have enough Mana to cover the cost. The other is Rush is similar to the cheap WoTLK Classic Gold current Charge mechanic, but it does not allow attacks on the other Hero during their first turn.
