注意:

If the given call requires you to know the facing direction of a phantom, look at that phantom's opposite within the Split Phantom Columns | Lines | Waves formation. Hopefully that spot is occupied by a real dancer, in which case your phantom is facing the opposite direction of that dancer. This is known as Assume Symmetry. Some callers believe you should always do this; other callers believe you should never do this (I am of the latter opinion). EN: 50

Add Chinese
If the caller says Split Phantom Waves, then you have more information about the facing direction of the phantoms: they must be in Waves! EN: 60

Add Chinese
Imagine there is a brick wall dividing the two halves of the set. This can prevent you from crossing over into the other half of the set. EN: 70

Add Chinese
Shape-changing calls are allowed. Do the given call, keeping track of the phantoms, and breathe as necessary so that the two resulting formations are adjacent to each other. EN: 80
