Im a player thats come back after years and see a lot of things have changed and a lot of new characters. Iv come on 4 months back and noticed a lot of my characters i bought have sky high prices so iv sold a few. Just need advice on building a few EFC decks that work really well for each stage. Clintz arent an issue so let me know guys what works well together.
You mentioned that you need EFC decks for each stage, but since you are an older player returning it sounds like you may be thinking of the old EFC system that had an increasingly limited number of cards from each clan being available to you as you climbed the ladder, with only the most recent 10 being available in z palace. This is no longer how EFC works, and it has since been reverted to the old system in which all cards are fair game, except for those from the universal staff ban list and the seasonal player vote ban list.
While I don't have a specific deck to recommend, it is worth it to take the time to get the legendary cards, as they are never banned are generally among the most powerful cards available to a clan's EFC lineup. It is especially worth your time to get the legendary cards from the arcade, as you get the legendary cards relatively quickly and will also gain ~ 1 million clintz worth of prizes along the way. If you are looking specifically for strong decks, you can go to the public presets section under the community tab, and can browse an almost endless amount of very strong decks posted by the best EFC players this game has to offer. From there you can choose one that fits your personal style and available cards. Good luck in EFC
