I wanted to make my game feel like an RPG, so I wanted to be able you to choose what skills/perks/items does your hero has before beginning fighting. Every hero card will still have its unique stat combo and effect, but you can add 2 more through special ability token. The hero can only equip ability tokens of certain types that fit the hero.
What do you think?
I think, its a good idea.
In one of my older designs - the players could attach cards to their hero cards. on the border of the hero cards where small descriptors showing what cards can be attached to that border. so skills and spells are each represented by cards wich can be attached - provididing hundreds of combinations to customize heroes.
