Games Workshop has a bit of a 2-for-1 in this update. If you want to check out the Illusionary Might Rivals Deck for Harrowdeep, you can. But they've also got a balance update for all of Warhammer Underworlds tucked away in there. So, if you play the game, you'll want to give this one a look-see.
From the article:
Blackpowder’s Buccaneers and the Illusory Might deck are both up for pre-order this weekend. We’ve already seen what the ogor pirate Blackpowder and his menagerie can do, and now it’s time to see what’s inside this new pre-built deck.
We’ve also got a few rules and balance updates for Warhammer Underworlds to download below, alongside some designer commentaries.
