What I have in mind is this: For your 2nd and 4rd win in a Serie you get to choose the set, where the foil is from, for your 6th and 8th win you get to pick the set and the culture too, and for 10th and 12th win you get to pick the exact rare you want. Or something like that. You get to choose the rares for Top 4 as well.
I mean how many of you got some Expanded crap that you cant use, after you just Top 4-ed a League or 13-0 a Serie of 50-100 players? Hardly exciting for your efforts. I dont think what I suggest is that unreasonable, it rewards good play, and besides there is usually only 1 person with 12 or more wins, and 2-3 players with 10 or more wins, think they deserve the right to pick the cards they want.
Random foils in the Top 4 are even more depressing and dont feel right at all.
Also, please explain your vote here, so we know its not just random troll or something.
