This is the New Card Zoobot that will be released with the new Hearthstone adventure One Night in Karazhan due for release on the 11th August.
The card text reads: Battlecry: Give a random friendly Beast, Dragon, and Murloc +1/+1. It’s also a Mech card which gives it some great synergy in the Wild format with all the old mech cards.
There is an obvious connection with the other card we’ve seen called The Curator, which draws a beast, dragon, and murloc from your deck and is also a mech. I reckon there will be more cards to follow that synergize with these mechs and there are already some fun decks these can be included in.
