This card cannot be Normal Summoned or Set. This card cannot be Special Summoned except with "Sky Union". This card is unaffected by the effects of your opponent's Spell and Trap Cards. During each of your End Phases, Special Summon 1 "Robot Token" (Machine-Type/WIND/Level 1/ATK 0/DEF 0) in Defense Position. That Token cannot declare an attack. While you control a "Robot Token", your opponent cannot select another monster you control as an attack target, except "Robot Token".
