The Witchwood card tracker

The Witchwood will be Hearthstone's first Year of the Raven expansion, and is set to introduce new keywords, deck-building challenges and another single-player challenge mode.

The expansion will feature 135 new cards and two new keywords: Rush and Echo. Rush lets a card attack the turn it is played, but the card can't attack heroes that turn, while Echo lets you continue playing the same card as long as you have the mana to play it again.

There is no set release date for the expansion yet, but it will release in mid-April, and when it hits, Whipsers of the Old Gods, One Night in Karazhan and Mean Streets of Gadgetzan will rotate out of the standard format.

The new single-player mode will be a new form of Dungeon Run called Monster Hunt that will feature four single-player-only classes. Players who log in when the expansion launches will receive three free packs and one free class Legendary.
