Kaiba Corporation Common (海馬（かいば）コーポレイションノーマル Kaiba Kōporeishon Nōmaru), is an OCG-exclusive rarity introduced in Yu-Gi-Oh! The Dark Side of Dimensions Duel Set and Yu-Gi-Oh! The Dark Side of Dimensions Theater distribution card 1. These cards are just like Commons, but have a hi-tech pattern and the "KC" KaibaCorp logo coating, with similar holo coloring as the Duel Terminal Normal Parallel Rare or Millennium Rare cards.
