Speaking of not having the coins to make upgrades to your lineup...

Grind through Challenges/Solo Battles/H2H/etc. Doing so will reward you with plenty of coins over the course of time.

Leveling up in not only Competitive and Seasonal field passes, but also field passes that are a part of some programs rewards you thousands of coins at a time. Make sure to pay attention to these field passes, unless you are fine with missing out on potentially hundreds of thousands of coins.

Now for some Auction House talk. Learn how to take advantage of the price crashes and fluctuations that occur on a semi-frequent basis in the Auction House. Buy players when they are under their overall's training value and sell them on days when training is in demand. Find players that are selling for high prices on the Auction House, and see if it is cheaper to build their set so you can auction them off for some nice profit. MUT.GG user Gent (one of the more knowledgeable and trustworthy users on this site for sure) sums it up really well, so I'll just copy and paste his words as I serious cannot say it any better myself: "Investing in cheap training and holding until it goes back up is how I've made 99% of my coins this year. I do the occasional sniping/flipping, but the most consistent way I've made coins is buying training on cheap days (Saturdays are usually best) and then hold until a new LTD in rerolls comes out then turn and sell the cards. For example, when everyone got their free TOTW pack on Tuesday, the TOTW market got flooded with 92, 93, 94, and 95 overall TOTW cards that were selling for under 2 per training. I bought a bunch of those cards and am going to sit on them until the profit is at an amount I'm good with then I'll start listing them. It takes patience though. I could be sitting on these cards for another week before I can sell for a decent enough profit, but that's okay with me as it will make me more coins than selling them for 5-10k profit each right now. If investing isn't what you're interested in, sniping and reselling is always the easiest way, but it's more difficult as there are obviously a lot more competition. You could always find expensive cards on the AH that sell consistently and see if you can't build their set for cheaper and sell for profit, but again, more competition there as well." (1-19-23)
