Question

I’m trying to complete Challenges in order to get the pack at the end of 7 days except one of my challenges is “Acquire a new player. Purchase a new player from the shop”. This literally makes no sense. I don’t have the luck to score on a free agent and just spent $7 (real money) to get 600+ stars and Drew condition drink and level increase leaving me low in stars and I have 113k in pts except don’t want to risk the wager of bidding in the point system auction. What do I do ?
