For my first team at level 28 I'll spend up to 20 tokens on auction. 30 for the right player at the right time through negotiations. Rarely I'll buy the most expensive recommended player if it's a position that I need. Never, ever, ever touch the rubbish from the scout list.
Just started a second team. First season. Auctions at level 1 are a nightmare. Forget everything you've ever learned about getting players. It's bedlam! Tokens almost gone, money gone, 11th place. It's more fun at level 1 than level 28.
