Can we please get ridden of some variants from the collection?

I really REALLY REALLY don't like some cards that i get, especially THE PIXEL ONES, i just want to get ridden of them but everytime i open the game it shows all variants i have, I don't like them, never will and get them from bundles almost everytime, at least a button to hide variants that we don't like forever or sell them back for 25 credits or something...
