Alongside flat rate, escalating, nuclear etc. is an option saying 'random'
When selected, players are unable to see which randomly selected spoils setting their game is using. They will only find out when they start cashing spoils
Fog is applied. When an opponent cashes a set, the game log will merely say 'opponent x has cashed a set of spoils'. This will keep the mystery in place for each player yet to cash
How this will benefit the site and/or other comments:
It would be even better if each spoil was a different type. If one spoil was flat rate or escalating, it would get +2. Then the Escalating share would get 1/3rd of the current bonus and the escalation would increase 1/3rd to the next level. The Flat Rate would score 1/3rd for the actual composition of the cards. (If the card was green and the other 2 cards were red and blue, he would score 3 for 1 flat rate spoil, 7 for 2 and 10 for all 3). Nukes and Zombies are easy to deal with. None spoils can still be cashed but don't provide anything. No +2 or anything.
