I'm looking to help new players with boosting their rank. How far and how fast it depends of how many epic/legendaries the account has. If the account is bright new for example without any unlocked cards, I can only guarantee boost to rank 10 as to go further than that it requires some locked cards.
For prices we can discuss, but a general idea is:
Rank 25-20 = $6
Rank 25-15 = $15
Rank 25-10 = $45
Rank 10+ PM me on skype.
