amazing effect, no wonder it's worth that much. you can negate 1 battle each turn, combo this with dark door and/or gyroid. :)

Combine with Temple of the Kings which lets you activate traps the turn they are set and you can activate it as many times as you want per turn.

good card effect, but josh is right. anyway im almost shure this is the only counter trap card (i know its not a counter trap) that resets itself.

ok card effect. Just so the rulings are clear You can only activate it once per turn. When it sets itself back think game mechanics. What happens when you set a trap? well you can't activate it for the turn its set. Thats what the text on scrap iron means.
