BRUTUS!

Betray your friends. Rule the arena in this card game. Enter the arena of Brutus: each player embodies a Ludus, a house of gladiators whose survival depends on the wise choices of its leader, the Lanista. Use their unique ability to your advantage. Bet wisely on which fight you'll win: whether your gladiators win the laurels of victory or lose miserably, each of them will be one more step toward your rise. —description from the designer
