Runs -- normal

HIDDEN keeps a run off the board, out of the patch counts and out of the high-score check, while it stays available as an arena opponent. That is what seeds a fresh board with starting champions.

A hidden run is a RESERVE, not an equal: a roster is filled from the real runs first, and the hidden ones only top up what those left over -- at the end of the list, so they are the last champions fought. Once there are enough real runs near a player's level, hidden ones stop being sent out at all.
