We still don't know if this card will be included in the Adapt effects rotation though. Clever plays can find ways around the Battlecry, though, so making a new keyword like Rush should allow the card designers some more flexibility.
Along with a bevy of new cards, Witchwood will also introduce a new Echo keyword. The heroes all have a unique hero power and their own cards to help build new strategies, and each encounter you clear nets you loot in the form of cards to improve your deck for the remainder of the hunt. If you're really keen to learn the cards, the Hearthstone team will host a livestream on its Twitch channel at 11am PT on March 26th where it will start revealing them.
A new Hagatha card, which Blizzard chose to leave as a mystery for the time! It will launch two weeks after The Witchwood expansion. "The citizens of this proud kingdom, who can shapeshift into ferocious wolf-beasts known as worgen, are bringing the fight to The Witchwood with tooth and claw-and soon, Hearthstone players will join the pack and help them face down the horrors within". One reduces your hero power to cost one mana if you've only included even-numbered cost cards in your deck, while another upgrades your heroic ability if you've only got odd-priced ones.
"Rush" minions function much like Charge minions in that they can attack immediately after being summoned, but can only attack other minions.
"Echo cards can be played multiple times on the turn you play them".
In a humorous announcement trailer posted earlier today, the developers of the beloved card game, Hearthstone, teased a new expansion: The Witchwood! Called Monster Hunt, players will be tasked with venturing deeper and deeper into The Witchwood to cleanse the forest of darkness.
As usual, Blizzard has opened pre-purchases of a large card bundle with an exclusive card back for those who purchase it. Blizzard is also promoting the game by offering gamers three free packs and a random Class legendary card, both of which will be from the expansion, just by logging into the game after the expansion has been released.
