Maybe it will help someone. Was lucky and got 3 medals on first try (with total team power of 220k + 75k helper). Thou from starting default set-up I moved one squad from starting spot close to random node to the free starting spot above to the right of it. Red arrows are teleport paths, orange ones show direction (for starting spot, or default direction after unlocking node B). Blue is a path that gets unlocked with node B. As I am done with gacha (all 100 rolls on all 11 resets) I am not willing to drop 80 more stamina just to see where the last teleport leads to .
