Morph

What is Morph?
Morph is a keyword trait used to depict heroes who have multiple forms and powers, and their ability to shift between them when needed. This is most commonly seen in some of the Kamen Riders, who have numerous forms and designs for whatever challenge they're up against.

When your opponent plays a unit without Morph from his hand, you may choose a unit in your Power or Command Zone with the same keywords as a Morph you have in your Rush Zone. They switch locations, in the position they are currently in (Held or Relases).

For instance, Kamen Rider Black RX has the keywords Kamen Rider, Male, Cyborg, and Hybrid Energy. When he uses his Morph trait he can switch positions with his alternate forms Robo Rider and Bio Rider, as they both have the same keywords.
