I have tried some cards solo to get that adept HC...after some loss in 3wins card i took a break... after some hours i started again and i managed to get six wins in a row,then i lost mercy.i won the next one and game didn't gave me access to lighthouse....i shred the card when i realised that in the beginning i have started with my mercy lost from previous plays...Its not so clear that mercy is gone and i believe a card with 0 wins should always renew by default...i am so disappointed because i believed until the end that i went flawless.
