Just this past season I have been trying to ensure I play more often. Whilst my main account is using Splintermate, I regularly add a few extra battles manually, especially Brawls which I compete in entirely human.With the latest selection of reward cards being Soul Bound it really has been luck of the draw. I have managed to collect quite a few but all in a low BCX that honestly will not accrue too quickly so over time, consistency will be key.
