"Besides, singles prizes at the beginning will be crazy anyway."
Will they change on their own, or only due to players' actions? The problem I see currently is:
- noone will sell good cards, because the starting price is very low,
- noone will buy good cards to drive the price up, as they are unavailable (and will not become available when someone sells them, due to starting sell price being low and noone selling).
Another problem I see is heavy devaluation of foil cards. Foils (especially C and U foils) should cost way more than 4 copies of non-foil card. A foil is found on average in one out of 6 packs, so for each foil card you have 65 non-foil ones (including 6 rares). This goes down a bit due to C and U foils being given out also as league prizes, but still I feel foils should be worth way more than the merchant values them currently.
