I accidentally traded my flawless card for a glaive, i didnt think my card was literally going to be used up. Im not good at pvp anymore, this card was a fluke, my luckiest streak of solid teammates helping me win, I havent been flawless since D1, i was having fun in trials but now that i tossed my card away my motivation is shot, theres no way somebody could look at my acount and undo it is there.
good news for you, buy a new card and reach 7 wins. no matter how many times you lose on that card, you can still get an adept from winning a game after those 7 wins, however the drop chance is pretty low
Pick up any other card, grind for 7 wins and you can continue farming again. (you don't have to go flawless again - it can literally be 1 win 1 loss on repeat for example
