cr:1.3.4
A card is distinct from another card if one or more of its faces has a name and/or pitch value the other card does not have.
Example: Sink Below with 1 pitch (and a red color bar) is distinct from Sink Below with 2 pitch (and a yellow color bar).
Example: The split-card Null||Shock is distinct from Vaporize||Shock because one of the names (Null) is not present on Vaporize||Shock.
