The Thunderstruck Challenge 1 Squad Building Challenge (SBC) is a limited-time puzzle in FC 26 Ultimate Team that lets you trade in a relatively low-rated squad for a solid pack reward. It is part of the Thunderstruck promo content cycle, and it’s designed mostly as a fodder or value SBC: you use cards sitting in your club and turn them into a tradable pack with a chance at strong players or promo items.
Because this challenge has only one squad to submit, it looks simple on paper. However, the chemistry requirement is quite high compared to the quality of players you’re allowed to use, which is why many players get stuck trying to meet the chemistry threshold while using cheap cards.
This guide walks you through:
The Thunderstruck Challenge 1 SBC consists of a single segment. Here are the full requirements you need to meet for that squad:
This combination of rules forces a careful balance:
Because of this, the most efficient way to complete Thunderstruck Challenge 1 is to build around a few strong links (same league, nationality, or club in legal quantities) and then use flexible players to bridge into other leagues. The aim is to get chemistry while avoiding expensive meta cards.
Below is a sample low-cost solution that fits all requirements and maintains solid chemistry. Prices will vary depending on market fluctuations and current promo content, but you can use this as a template and replace players with similar cards from your club.
This example focuses on using common Golds and a few Silvers, prioritizing league and nationality links to reach the chemistry cap:
Why this works:
This exact squad is just one example. If some of these names are expensive on your platform or you already used them in other SBCs, you can substitute players from the same leagues and nations while maintaining the same structure of links. Always check each player’s league and club before buying, and aim to keep a tight set of connections in defense and midfield.
If you prefer to build from scratch with what you already have in your club, follow this workflow:
Using the squad builder and ‘Search your club’ options can save you a lot of time and coins. Try to use untradeable club fodder first, then fill gaps with cheap transfer market cards.
Once you submit your squad, you earn a tradable Rare Gold Pack. Here’s what that usually means in FC 26:
Because this pack is tradable, it has a higher long-term value than many untradeable SBC rewards. Even if you don’t pack a top-tier promo player or walkout, you can still recover part of your investment by selling consumables or mid-rated fodder during content spikes, such as Team of the Week or other SBC releases.
When a major promo like a Best-of Re-Release or a high-profile event squad is in packs, the value of opening tradable Rare Gold Packs increases significantly. This is often the best time to complete fodder SBCs like Thunderstruck Challenge 1, because you are effectively giving yourself a lottery ticket for special cards while recycling low-value items in your club.
Even a relatively cheap SBC can become expensive if you rush and buy the wrong cards. Use these tips to keep your costs under control and meet the chemistry requirement without frustration.
Before spending any coins, check your club for untradeable Silver and Gold players you don’t use in your main squads. These are ideal for fodder SBCs because you can’t sell them anyway. Focus especially on:
It can be tempting to throw in any 81+ card you don’t like, but some players have hidden value due to their in-game performance, chemistry links, or popularity for objectives. Before submitting your squad:
In modern FC chemistry systems, the easiest way to hit a target like 31 chemistry is to stack league and nationality links rather than relying only on club links (especially since you’re capped at four players per club). For example:
Small tweaks, like swapping one off-league defender for someone from your main league, can give you 2–3 extra chemistry points instantly.
Card prices tend to rise when new SBCs are released and drop during heavy pack supply (lightning rounds, big promo content, weekend evenings). If you’re short on a couple of Rares or specific league players, try shopping during off-peak times when there’s more supply and less panic buying.
While clever SBC planning can save you a lot of club resources, building a truly competitive Ultimate Team throughout the year still requires a steady flow of coins. Grinding menus, trading, and playing matches all take time, and not every player has the hours to keep up with the in-game economy. This is where external services can help you bridge the gap in a safe and efficient way.
ItemD2R.com focuses on providing game-related services for football titles and other online games. If you are short on budget to complete SBCs like Thunderstruck Challenge 1, or you want enough resources to constantly participate in promo content, you can consider using coins ea fc 26 from ItemD2R.

With a stable coin balance, you can instantly buy the fodder cards needed for SBCs, experiment with new formations, or upgrade key positions when the meta shifts after patches and promos. It becomes much easier to take advantage of opportunities such as flash SBCs, lightning rounds, or limited-time cards that fit your team perfectly.

When combined with smart SBC execution like in Thunderstruck Challenge 1, this strategy can help you steadily improve your club value, accumulate high-rated fodder, and stay ready for the next big SBC or promo squad. Always make sure to follow EA’s terms of service and consider your own budget and time investment before using any external services.
In most cases, yes. The SBC cost is relatively low if you use club fodder and cheap Golds, and the reward is a tradable Rare Gold Pack with at least one 81+ player. During major promos, the chance to pack a valuable special card or walkout makes this SBC very good value, especially if you were not using the submitted cards anyway.
At the time of writing, Thunderstruck Challenge 1 is generally a one-time completion SBC. Always double-check in-game, as EA can change formats between promos or release follow-up challenges (Thunderstruck Challenge 2, 3, etc.) with similar structure.
Thunderstruck promo SBCs usually have a limited run, often a few days up to a week. Check the SBC menu in FC 26 Ultimate Team for the exact expiry timer. Try to complete the challenge while key promos are still live, so your tradable pack has access to as many special cards as possible.
If you build smartly with club fodder, you should aim to spend only a small amount of coins, often under the cost of the actual Rare Gold Pack in the store. Treat this as a value SBC: the moment your total spend approaches or exceeds the store price of the pack, you should stop and re-evaluate your squad, looking for cheaper replacements or more untradeables.
Start by changing formation and checking alternative positions in your club (e.g., moving a CM to CAM or CDM spot, or a RM to RW if chemistry allows). If you still cannot hit 31 chemistry, buy a couple of cheap players from the same league and nation as your core. Using a small number of targeted purchases is usually much cheaper than completely rebuilding the squad from scratch.
Ideally, open your Rare Gold Pack during a time when high-value special cards are in packs: Best-of Re-Releases, major promo squads, or new Team of the Week cycles. This maximizes the potential value of your reward and increases your chances of pulling something you can either use or sell for a profit.
By understanding the requirements, approaching chemistry logically, and using your resources efficiently, Thunderstruck Challenge 1 becomes a straightforward and rewarding SBC for any FC 26 Ultimate Team player. Combine these strategies with smart club management—and external coin options if needed—and you’ll be well-prepared for the rest of the Thunderstruck promo and beyond.
