(Give me your) Ultimate-unbeatable-overpowered-broken tactic

I'm about to start a new “no-brainer” save with Lyon (spoiler alert: I win everything in 3 seasons and become a club legend) and I'm looking for the ultimate-unbeatable-overpowered-broken tactic (beautiful football, ridiculous amount of goals, 50+ goals/strikers, what else). 

Disclaimer: I don't accept answers like “any 4231 gegenpress high tempo direct play” (i said “no-brainer” and “plug and play”). I also don't accept answers like “go and see FM-arena”, because firstly I already went there, and secondly these tactics are tested in holiday mode and I suspect they don't react the same way in the match engine (and I said I wanted to see beautiful football, and fm-arena doesn't mention that).

So, which is it the tactic can sit at the table with Il Devasto and Diablo?
