I think tournament prizes should be randomized or maybe even a ladder prize.
Option #1 prizes are randomized so you could get the normal box prize or maybe other boxes or players or whatever it may be.
Option #2 ladder reward so consecutive wins is key. Won #1-4 would be tournament boxes like normal. Box 5 would be say an Evo box. Boxes 6-9 would be tournament boxes. Box 10 would be a special players box like what we get for gifts. And so on. But remember you have to win multiple tournaments in a row.
