For 4 seasons, the Auction has served me well. I tried a couple of Negos during Level 4 but didnt get any accepted by players 3-4 Level above me. I suspect they play via mobile or are not playing anymore. Gave up negotiating. I bought one from the scout list that season and he has served me well.

It's all a matter of preference.

If you have patience and some tokens, buy from Auction.

If you have a lot of tokens, get from the Scout list.
