Trump has been hard at work building decks with cards from the last wing in the adventure One Night in Karazhan. This is the Trump Burgle Rogue Deck w Ethereal Peddler he was using on stream.
This is usually enough to have a huge tempo swing turn. You will often have cards reduced to 0 mana and will even pick up some synergy. The most annoying part for your opponent is that they can’t play around what they don’t know is coming. 🙂
