All passive skills (buffs, summons, shields) will activate in the order that they are dragged onto your team. Move your gaara around and put him back for him to be considered as being "put in last" then he'll be able to shield narutos clones
thanks i get it, now the clone have shield the clone but how to make main to move than gaara? i want to make her clone to be shield also, i tried like you said but only naruto move 1st
moving your main will count as "dragging in" so move your main around, then naruto, then gaara
