Yikes, save your coins until a "market crash" usually when a new popular promo comes out an then be vigilant with checking prices here on Mut.gg and then snipe the card for maximum value stick with a few players that you want or need that you cant get free through challenges or promos, your not necessarily targeting the newest cards but a step down from them that rich players are discarding when THEY get the newest cards .
For now, work on free cards and saving coins, if you can get the Field pass premium pass (1500 points), its the best bang for your buck that you can spend real money on (under the Field pass menu), you'll get a good amount of coin packs, tons of free tickets to upgrade the free cards and the free cards themselves. follow the daily objectives and weekly objectives in the Field pass objectives section and then work on completing them by doing challenges or in the cpu events under the events tab or the vs cpu tab,
Save any "collector tokens" that you get for now,se what you get in the free or bnd cards then use them in the sets for more expensive cards that your looking for after to fill in your roster.
Doing these challenges and daily/weekly field pass objectives will get you a ton of level upgrade tokens(90. 91, 92, 93, 94) that you can upgrade the free season 5 field pass players that you will get in packs when you reach them on he field pass.
Immediately do the predictor sets, upgrading your 85 ovr DaQuan Jones, Tre Harris etc that you'll receive in the predictor packs (you use victory tokens to do this), you'll get victory tokens for correct picks that you make after this weekends divisional round games plus in the victory voucher section of the store you can use vouchers to buy victory tokens as well.
Do the current cpu event for a good 94 overall receiver under the events section, plus it counts toward your objective and gives victory vouchers as well.
I'm sure there's more that I'm forgetting, smarter people can chime in, but go get freebies and save your tokens and coins. Try pick offensive and defensive line whenever possible for the free picks, they will last you longer.
good luck.
