Kikai

Kikai monsters are all EARTH Machine-Type monsters. There are two types of Kikai monsters and they function in different ways but help each other to be more powerful. The two types are Kikai Ouhi and Kikai Ouja.

Naming
Kikai means Machine in Japanese. Ouhi and Ouja means Queen and King respectively so Kikai Ouhi means Machine Queen and Kikai Ouja means Machine King.

Play Style
Unlike other archtypes that are weak when faced by cards that remove them from play, Kikai monsters actually thrive in the remove from play pile. Kikai monsters base their effects on the usage of the remove from play pile to become stronger so unless your opponent stops the Kikai monsters from removing themselves from play then Kikai monsters are unstoppable.

Kikai monsters are able to swarm at an unparallel speed which could be compared to the Six Samurai and Synchro Summon their more powerful monsters. Due to the fast rate of swarming, Kikai monsters can Synchro Summon their stronger forces easily like Level 9 Synchro monsters.

However, a single Imperial Iron Wall will be able to stop the Kikai monsters from making their moves. Another weakness that Kikai monsters have is that the entire archtype is weak to Spell or Trap cards and only a few can get rid of Spell or Trap cards so a heavily defensive deck can stall out the Kikai monsters.
