Once per turn, you can discard 1 card to Fusion Summon 1 "Cyber Blader" by sending either "Etoile Cyber" or "Blade Skater" from your field to the GY as 1 Fusion Material, and the other material from your hand, field, or Deck to the GY. That "Cyber Blader" gains 400 ATK. This Skill can be used twice per Duel.
