i personly wish i could pick more than one as i want more lvl ups(because its boring to play not takes so long to get 10 lvls even a 1* would make it funner) and i want the max of 3 of a card in a box as when i do spend i usaly get fd over lol i also want older sets cheaper but thats not that important as the other 2
in other words 1 is to keep me playing and not getting bored(which is important bored people stop playing

) and to help noobs and the other is to make it so i dont feel riped off when i do spend which in turn makes it more likely i will spend again(ie if i am looking for a card and i get a box if i get like half of the box muti copys of a few cards id say **** it and not get any more if i got 1 copy of that card id proberly spend more on another box)
