12K can't even pay wages of a single player. That's for Level 1 players...
Without all those free video boosters, how many tokens will the power training cost?
Just gonna have to use friendlies instead of training for extra boosters, I'd use that AEPRE FC B account as a punchbag team and set it on light tackling and illegal formation so you beat it easy each time so you get tons of blues as well.
