Diecathlon

From BoardGameGeek:

Diecathlon is a co-op deck-building die-crafter that pits you against waves of old and new legends in a cyberpunk Atlantis arena. Each wave of enemies represents a battle in the arena. In each battle, you will use the cards from your deck to customize your player mat, which represents the sides of your six sided die and what it will do for you in the battle (attack, defense, heal, etc.). You and your teammates will then roll your dice, and get a chance to trade them with each other to maximize your turn. Your deck also represents your health pool. As you take damage, you must discard cards from your deck (not your player board). If you have no more cards to discard for damage, or to draw at the beginning of your turn, you are knocked out. Between battles, you will have a chance to gain new cards for your deck, or trophies that give passive bonuses. Whether you engage in the single-run skirmish or the rogue-lite campaign, you'll find gameplay that's easy to set up, mechanically unique, and wildly fun! Rogue-lite mode: Play, die, upgrade, repeat in a grueling challenge that pulls no punches. Make it through 10 waves and defeat the boss to win. Skirmish mode: one shot, one death. Make it through an accelerated 6 waves which provide faster loot grabs and get you to the boss faster. -description from the publisher
