I use 178 tokens every month... ( I started to buy tokens the 5th month) ...and, just to buy 1 player of the academy and 3 players of 6 stars...
I won 5 leagues, 1 champions (have 2 finals, 1 win-1 lost) and 1 cup (I have 3 finals, 1 win-2 lost).... and now I play the 9 season...
at now I have a team at 1st level, but I do the tactic to don't wast tokens, simply I was training the 1st month without assign training points, I end at 8th position, and, now, in the 2nd month at level 1, I assigned the points. I have simply 3 players of 5 stars, and 3 of 4 stars, the other have 3 all... and I am 1st in the league with difference....

so, at elevel 2 be sure with a team full of 25 quality team, you will do a great work...
one thing I really wanna say to you is that you don't need all this tokens to have a good team, at level 4 try to have friends of better level, that have players of 5 stars that they don't use and you can buy. Try too, to be in the matches and change a player, to recive a green booster, another as a gift, and another if you do and see a friendly match. you can use this green boosters to train a player from the academy.. or a good 5-6 star player that trains fast, and read in this forum there are very good tactics to have good team without waste all that...
you can waste 300 tokens for a 6 players of 6 stars? of course, and sure doing that you will be the Mr. Nº 1, but, you can waste more effectively. and what I said at level 4 you can have friends of better level, that can buy 5 star players that they don't use for 1 token, so, keep learning, and see all this forum
