It's a fun deck to play in the Theme Chronicle event. The small psychic Kozmos special summon the big machine ships from your hand. Kozmo Tincan is your main searcher for the big ships. Kozmo Farmgirl can surprise OTK your opponent if she gets a direct attack. Kozmo Dark Destroyer is your main ship to pilot because it can easily break boards with its targeted destruction effect and big attack stat.
The TCG's Psychic Support
The following cards were initially released in the TCG's Phantom Knightmare (PHNI) set, but now they've found a home in Master Duel!
Psychic Processor is a great card whose main effect allows you to special summon up to 2 Kozmo monsters from your hand and enables the monsters that were special summoned by this effect to attack directly for the rest of the turn. I've stolen quite a few games by using this effect to attack directly with Kozmo Dark Destroyer.
Psychic Arsenal is a decent consistency booster for decks that run low-level psychic monsters and high-level machines. These requirements make it a natural fit for Kozmo decks. Its first effect allows you to target a psychic monster you control and pay 200 life points times its level, then add a machine monster with the same attribute, but a higher level from your deck to your hand. Target a light psychic Kozmo to add Kozmo Sliprider or Kozmo Forerunner to your hand. Target a dark psychic Kozmo or Psychic Processor to add Kozmo Dark Destroyer, Kozmo DOG Fighter, or Kozmo Dark Eclipser to your hand. Psychic Arsenal's second effect allows you to banish it from your graveyard to add 1 of each of your banished psychic and machine monsters to your hand and to the bottom of your deck. It's another decent effect that helps you recover during long grind games.
