How to get XP quickly in MyTeam
You might think that getting XP would be as easy as playing one of MyTeam's game modes, but it isn't. To get XP in MyTeam, you actually have to complete challenges. These challenges are called Agendas and there are different agenda goals for the current season and the life of the game.
Season agenda
The Season Calendar offers a number of ways to quickly earn XP. These goals are mostly goals that you can sit down and unlock in one session. With things like daily goals, times, and weekly goals to hit. Simply go to the Season Calendar under the Season 1 tab of the MyTeam main menu to view your goals.
Along with these daily and weekly objectives, there are also player objectives among the various packs available. For example, Rip Hamilton is one of the Clutch Packs players and he has several challenges to complete, which will require you to use a Rip Hamilton card to complete. Completing them can give you big XP. Of course, there are many other lenses similar to this one.
The best way to do this is to focus on the goals you can achieve, and try to complete multiple goals in one game. While it might seem like a long time, if those goals require points scored, assists, or other stat heavy goals. a good place to do them is on Pro Domination difficulty games. Pick and choose your goals and you'll start earning pretty quickly, with the rewards being things like tokens, packs, and Ascension Board Trials. Take those winnings and reinvest them in packs to attract players that you can use to complete other challenges. If you are having trouble attracting the players you want through pack openings, you can try purchasing them directly from the Auction House.
Lifetime agenda
Lifetime Calendars really shouldn't be about if you're trying to get XP fast. Most of the challenges in the Lifespan section of the calendars will take you a while. These include actions like earning hundreds of stars in Domination, completing collections, and more.
The fastest way to earn XP
There really is no shortcut to earning XP. What you want to do is limit the number of replays you have to do when failing challenges in long games. Playing at the Pro skill level in Domination can make it very easy for you to get points, rebounds, assists, or other stat requirements. However, there are also some small requirements that can be met in a much shorter game like Offline Triple Threat. It really depends on what challenge you are trying to complete for which mode you want to play. Some challenges will require you to play in a specific mode to complete them.
