As If Adjacent

Some effects allow movement 'as if adjacent' e.g. Minecart Madness. If it matters, the controller of the movement effect decides the cardinal direction when a unit is moving 'as if adjacent.' For example, if you have a Waypoint Portal active and you want to move your East-West Dragon through it, you can choose to consider the movement horizontal and Move Freely, even if the two squares are not the same row. Similarly, a Dalcean Phalanx could step through a Waypoint Portal to a square in a different column by declaring the proper cardinal direction for the 'as if adjacent' movement. Units moving 'as if adjacent' do not cross any borders. Therefore, a Waypoint Portal would allow you to circumvent a Wall of Ice or Great Wall, which look for crossing borders.
