I didn't check my grammar on the blanks sinice they never where for puplic releashe.
I could fix that on no time.
Character, I don't think I need explain you what that is.
Each character should have their own special event, and there should be made tactic in other cards so you could build your own killer decks based on each character.

Edit:
I found this in my ''Old Junk'' dictory, it's a text on the game I was thinking on when I wanted to give a shoot for fun:

Character-
One character card must be used in each deck.
The player chooses his or her starting character to play with and plays the character card before the game starts.

Level-
The level stays in play after you played it, discard it if another level comes into play.

Event-
This card could have any effect that would change the game.

Adventure-
This card thats in play, no other adventure cards may be played if there's an adventure card in play.
An adventure may have an effect for your opponent only.

Weapon-
This card should stay in play after play it.
It should alow you use ammo cards or have a special attack effect.

Ammo-
This card may only be played if you have a weapon that alow you play it.
You may have mutiple copies of an ammo card in your deck.

Creature-
This card may only be played to special kind of charathers.

Spell-

Each player starts draw 7 cards.
Once per turn, start with draw a card.
You lose by run out of cards from your deck.
You win by let your opponent run out of cards.
You have 3 moves each turn, you'll have to pass your turn when you used your 3 moves.
Your moves can be used to play a card from your hand, playing a character card or an adventure card uses 3 moves whitch skips your turn.
You may have up to 4 copies of each card in your deck, your deck must contain 60 cards, no more, no less.
