Experiance/Rewards/Items for killing another army card

[Leif Kicker]

I was toying with the idea of making a deck of cards much like out of the old heroquest game for treasure items when you kill another players pieces.

Each time a army card was destroyed that player that destroyed the army would draw a treasure card, these cards would have things like
restore 1 life
add 1 defence to next dice roll
reroll an attack
add 1 attack to next dice roll
reroll an defence roll
move an extra 3 spaces
walk on water
even the good ole wandering monster...something like and angry orc or something that rolls 2 attack as soon as the card is drawn and goes away after defence is rolled.

thats just a few i could think of off the top my head...

1st question, I searched through the threads but wasnt sure what to search for, SO has this been worked on yet or is there another thread i could refer to on ideas.

2nd if this hasnt been started yet can you scapers toss out some more thoughts as i was wanting about a 60 card deck of treasure ranging from cards that help and hurt
