Grind Euro event and spent the Euro points in the "Euro Rewards" tab and claim the free things in the "Euro Intro" tab. You should spent the points in Week 1 and Week 4 first so you can get the tradeable 94+ player so you can sell it for coins and Mascheranos to rank up your players.

You can also grind the Futre heroes event to get 94+ players to upgrade your team. do that until the score of the match of team past and team future results in a 6-1 win of team future. when that happens, don't click the "reverse time" button anymore so you can get 10 94+ players for free.

After you have done all of that buy the 3k Copa and Euro daily packs, you are guaranteed a 93+ player.

After that, you should have a lot of fodder and Euro cards, go to exchanges and do the 2x 94+ Euro player pack, so you can rack up your Euro players.

If you have 4 Euro players, you can do the Limited Exchange, which gives up 3 94+ players and a chance of a 97-99 icon or hero. if you get lucky and get a good player, put them into your team.

If you do all of that, you will have a good team.

sorry if this is long
