The Arena is an Advanced Monster Room that was introduced with Boss Monster 2.
Ability[]
To activate its ability, you need to pick a regular or Advanced Monster Room from your hand, show it to other players and put it back in. You can reveal the same card several times throughout the game.
Strategy[]
A card that works best when holding onto another powerful Monster Room card. Good cards to use to achieve this card's full effect would include Beast Menagerie and Neanderthal Cave, Neanderthal Cave potentially being the best to use, since it has a rather hindering effect.
