Well
what you can do is farming greens which is more easier than token.
As I can see, you are from UK so there are many videos for packs.
You can farm 30 greens daily. In 3 days you can have 90 greens.
So, if you find a young fast trainer you can make him easily 6* player.
If you have 6-7 players like him, you can build a good team of 5* & 6* players without spending money.
