Mint-Tin Monster Mash-Up: Arenas

From BoardGameGeek:

Mint-Tin Monster Mash-Up: Arenas adds a ton of new content to Mint-Tin Monster Mash-Up! 12 new Cryptid Monsters: New Monsters with new powers! 2 new Mad Scientists: Dr. Evolve can re-make her monster mid-battle, while Dr. Time can pull off big swings in the Boost Phase by predicting his opponent's signal. New Automa: Dr. Fission is able to resurrect his creatures once per battle! Good luck! Updated Dr. Chaos: The most playtesting you'll ever get is after your game releases! It's become apparent that Dr. Chaos was a little underpowered. This new version corrects that and is meant to replace your current Dr. Chaos. 10 Arena Cards: These mini cards have fronts and backs like the monsters do and combine to create unique conditions every round! Arenas: Each round, the top card of the Arena stack is flipped and added to the right side to create a new Arena combo. If players meet the "If" condition, they place their Arena Tracker on the Arena. They can spend it that round to activate the Arena's "then" effect. -description from the publisher
