Outrigger Extension — Ruling

Effetto 1

This card's effect that prevents your opponent from targeting Machine Xyz Monsters on your field with card effects does not start a Chain.

This card's effect that Special Summons a Machine Xyz Monster from your Extra Deck using an "Infinitrack" Xyz Monster on your field as the material starts a Chain. (It can only be activated during your Main Phase.)
This effect targets 1 face-up "Infinitrack" Xyz Monster in your Monster Zone.
When resolving this effect, if the targeted "Infinitrack" Xyz Monster is in face-down Defense Position, the effect to Special Summon a Machine Xyz Monster that is 2 Ranks higher than it does not apply. (Even then, the part of the effect that prevents you from Special Summoning monsters other than EARTH Machine monsters for the rest of the turn is applied.)
