This is the Trump Beast Druid Deck w Menagerie Warden he was playing on stream. Menagerie Warden is as good as was expected, the only draw back to the decks seems to be how quickly you can unload your whole hand. This leaves you susceptible to AOE and is the most likely way you will lose.
It’s a fun deck, you can play it out quite aggressive as you’re not going to win the long game vs control decks with heals and card draw.
