A gladiatorial combat game that uses cards. Should scale from 2 - 6 players, cards are used for attack, defense, and events. Each card can have some, all, or one of the att/def/evt values and can be played together to increase a value, or in a sequence for sweet combo chain effects.
Something to be played at conventions. Fun, fast, good balance between flexibility and simplicity. Combos should be something special to behold, but not impossible to pull off.
Now someone else take the idea and add to it, change it, tear it a new one, or build from it! Aaaaaaaaaaand GO!
