The league pyramid
5 tiers of 8 clubs, and you start in tier 3.
A season is 14 matchdays: everyone plays everyone, home and away.
The top 2 promote and the bottom 2 relegate (Season rollover).
Every AI match is simulated by the real engine; the other tiers are played out as the game needs them (a look on the League tab, the paper's tier-1 check-in, season end) and keep those results.
Every club in the league wears a short clan tag before its name on match screens, like "[kbr] Kobrra Gaming", and an AI club keeps its tag for life.
Scrim opponents have none, and your own club can wear one once you own it (Your clan tag).
