Kozmo

"Kozmo" is one of two TCG-exclusive archetypes that premiered in Clash of Rebellions, the other being the "Kaiju" archetype.

The archetype consists of LIGHT and DARK-Attribute Psychic-Type "pilot" monsters and Machine-Type "spaceship" monsters who banish themselves to Special Summon other "Kozmo" monsters. The pilot monsters have a Quick Effect to banish themselves from the field to Special Summon any "Kozmo" monster from the hand with a higher Level, while the spaceship monsters have a Trigger Effect to banish themselves from the Graveyard when destroyed to Special Summon any "Kozmo" monster from the Deck with a lower Level.

The archetype also includes several effects that manipulate the player's LP, with some cards requiring the player to lose/pay LP, and some restoring them, similar to the initial Psychic-Type monsters.

Origin
The "Kozmo" cards seem to be based on properties from The Wizard of Oz and Star Wars. The pilot monsters are based on characters, the spaceship monsters on objects and vehicles, and the Field Spell Card on a location.

Playing style
The "Kozmo" strategy generally focuses on dealing large amounts of damage as fast as possible through winning battles rather than more complicated card combos. The "Kozmo" monsters themselves have few removal effects, so instead must focus on their attacks. Fortunately, their Summoning Quick Effects can make up for this lack of removal, and they can work well with both "Honest" and "Juragedo" to ensure damage.
