It's not mine. You can see the card "" from the anime, which reads as follows:

''If a Link Monster this card points to battles, its ATK becomes double its current ATK during damage calculation only. When this card leaves the field while it points to a monster(s), destroy all those monsters. You can only control 1 "Judgment Arrows" in your Spell & Trap Zone a Link Monster points to.''

It has all Top Link Arrows (top-left, top, top-right), and the bolded part is important.

Also, they are placed in the Main Deck.
