Yes you can open and sell however look at the inventory space, no matter how many u will sell, there will be rare engine cards that you won't sell and clearly space is the main issue here.

And when u get to placing top 1000 in almost every event, you will gain random boxes a lot faster than you can use. So inevitably you will start collecting them lik he and I.
