awsome thats heaps good to know, i was worried cause there wasnt much room left when i clicked "Show All"
Now i will only sell cards once i have 6 of them.
While you absolutely can do this, you might want to keep in mind, that some day in the far future (talking about YEARS) you will want to have
12 copies of each card, 6 unupped and 6 upped...
It only saves a tiny bit of electrum, but atm I actually only sell cards if I have more then 12 - Number of upped versions of this card...but i already have enough collected enough electrum for 2 upped decks, so i can afford saving that bit electrum...
But especially in the beginning, your very tight on electrum...so selling excess above 6 is absolutely ok, maybe even recommend. At the beginning i actually sold every upped nonrare card i didnt need for my actual deck...
