How much are you willingly to pay extra for background / KO animation? $1? $5? for me, umm.. I'm fine with normal background
Maybe different artwork of a card might work
or we can break the game by making alternate version of a card with different stats & different artwork (can be better, can be worse, can be the opposite of the abillity of that card)
*there will be no confusion since alternate stats will gonna have alternate artwork
ever imagine how nice Ghumbo
with +10 attack instead -10 att min 7?
or how about +2 power Mona
revenge / reprisal +12 attack Yumi
or 6/5 Dieter
or 7/4 Nahi Cr
or 8/8 Globumm
or completely changing the card such as ogoun kyun to 6/2 poison 2 min 3? or 7/1 poison 2 min 5?
to change it, it requires huge sum of clintz (from maybe 500-2K?) or you can unlock it for $1 per card..
*the market needs to add alternate version section of a card though.. or the card will revert back to normal if sold
it might help useless cards back in game, reducing inflation, more money for UR, plus we have something fun to do..
