Outflank

Secretly write down one of your units. X is half
its Scale, rounding up.
Play at the start of deployment to set that unit
aside as outflanking, not deployed.
Write down which neutral flank it will arrive on.
At the start of the Movement phase of Round 1
reveal which flank was chosen. In the Movement
phase of the Round 2, the unit can be activated,
the Rear arc of its base touching the chosen flank.
It cannot move any further during the phase.
