New deck: Rewards

[Brichs]

Yesterday, a friend was over, and we started talking about how you could make campaigns for LNoE, instead of just single scenarios.

We threw a lot of ideas around, and one of them was this:
Creating a reward deck.

How this would work:
You create a batch of scenarios, that are made to be played in succession. For instance:
Scenario 1: Escape in the truck base scenario
Scenario 2: The truck has run out of gas, and you must now escape on foot to a safehouse.
Scenario 3: You must defend the safehouse, while waiting for the military
Scenario 4: You've been safed by the military; now they've asked you to go back and destroy X, as this is the source of the zombie plague.

All heroes and items are carried over from one scenario to the next.
Depending on who won (and how fast you won), you get rewards, something akin to the heroes leveling up in an RPG.
Examples of hero rewards:
+1 movement
All heroes get to draw one card at the start of the turn
All buildings are Well Stocked
etc.

Example of Zombie Rewards:
+d6 zombies at start of turn
Zombie autospawn
One startzombie has graveweapon
Once pr game, can sacrifice 2 zombies to spawn a Zombie Hero
etc

Example of how a card would probably look:


Depending on how many cards I can think of, I'll either create 2 full decks of 54 cards (one for zombie rewards, one for hero rewards) or split it right up the middle (27 rewards for each). I'll then create an artscow deck - hopefully, before the current sale runs out on July 5th.

What do you guys think? And do you have ideas for rewards?
