First of all... What kind of friend doesn't have a Hive account? 😂
I like Zoo decks. I talked about Zoo some weeks ago and 2 different persons had no idea what a Zoo deck is. I was confused.
I think Nature and Death have the best cards for building Zoo decks.
I don't own Hydra yet but I see how you can have an armada of small angry creatures. Beside Trial of the Hydra I own all the cards and will try what madness the Hydra can bring.

!PIZZA for a buddy.
