Packs, the market and where coins actually help
There are two ways to get a player into a squad. One is opening packs and hoping, and the other is buying the card on the transfer market for a known price. The second is what coins are for. That is the reason EA Sports FC coins demand peaks in the same week as a promo, when target prices are visible and the market is deep.
Sizing an order is straightforward once you name the target. Look up what the card costs on your platform, add the market cut, and buy the amount that covers it rather than a round number. Buying twice with two deliveries costs more time than getting the amount right once.
If the whole squad is behind rather than one position, an account from EA Sports FC accounts can cost less than the coins to build the same club. Compare both before ordering, using the Eloboost24 buying guide for how the escrow works.
