Trade only? : yes, you go first
I got legend when i understood that getting legend has no impact in my real life has no prestige. When i got legend the first time i felt a momentary happiness and that's it.
What i normally do is, i set small goals every time i play, for example reach a certain rank. After two losses in a row i stop and take a break..i try not to tilt and the most important thing for me is to be consistent i always play one deck to legend and i say my plays out loud (like reading)..
So, try and be consistent, play your favorite deck/class and when you stop having fun stop. And the internet is your friend buddy, google your favorite deck, watch streamers who play this deck and learn from them..
Awesome.. from rank 2 to legend i saw only mages warlocks and paladins..my final boss was a shaman and i won at turn 5. I don't track my WR. Until now i faced kingsbane rogue only and i won every match up, Chief was hiding in the deck.
Against secret mage, i try to set up Chief so i can win at the same turn i play him..(proc ice block etc.)
I got legend with odd rogue from bronze(7bonus star from last month), played few games with kingsbane too.. from diamond 2 to legend swapped tour guide with chief inspector cause i was a facing a lot of secret mages. worked for me.
Great deck buddy..i got legend with the same list (bronze to legend in 13 days 7bonus stars) but instead of Doctor Krastinov im using Chief Inspector(diamond2 to legend) solid body with strong battlecry..i was facing (and still facing) alot of secret mages and this guy won me lot of games..i swapped it for Doctor to try your list!
