while i agree with huck that a "door prize" should only be applied to the losing players, I still have to say that i am torn on this issue.
Lets say there are two groups, group a can afford to buy new cards periodically while group b does not have that luxury.
If a person in group B continually wins events, they gain access to the newer cards that way, giving out a door prize to those who did not win from group b also benefit from this.
Here is why I say that it is not a good idea:
If two members from group A continually play with one member from group B (numbers can be modified), Odds would dictate that one of the group A players would win, now we have a player from both groups entered into the door prize pool.
This is now a coin flip, yes there may be cards that neither person has, but the greater benefit would be for the player from group b. I dont want to sound mean or cold but if a person who doesnt win cards either through winning the game or claiming a door prize (I am assuming it would be a random drawing), eventually, that person may give up, but if the only prize is found one way by striving to get either insane luck like i did in my first two clan games or winning by deck strength and strategy alone (like awe seems to do a lot), I think (through personal experiance) that morale leads to push the envelope and build better and better decks.
Yes we are all just on here to have a good time and yes it is fun to win, but I also have to play the devil's advocate here....a weekly drawing sounds good in theory but i still have my doubts.
