If this card is Synchro Summoned: You can target 1 Tuner in your GY; Special Summon it in Defense Position, but it has its effects negated. You can only use this effect of "Martial Metal Marcher" once per turn. A Synchro Monster that used this card as Synchro Material is treated as a Tuner while face-up on the field.
