Board/Card Games

Can you think of a video game you could emulate in cards, how would you go about it?

Fire Emblem would be an interesting one as its a tactical turn-based game with stats and different classes, and also has the weapon triangle which shows whats good against what. You could have some sort of real life turn-based combat system, and have different coloured cards better against others. They would have the characters have a card each, similar to the Pokemon card game.
