Infinitrack Fortress Megaclops — Ruling

Effetto 1

This card's effect that makes it unaffected by monster effects other than Xyz Monsters, and prevents it from being destroyed by battle with monsters other than Xyz Monsters, is a Continuous Effect.

This card's effect that Special Summons an Xyz Monster from your Graveyard and attaches an opponent's card to that monster as an Xyz Material is an Ignition Effect. (It targets a total of 2 cards; 1 Xyz Monster in your Graveyard and 1 card on your opponent's field.)
Special Summoning the targeted Xyz Monster and attaching your opponent's card to it as an Xyz Material happen simultaneously.
This effect finishes resolving by Special Summoning the targeted Xyz Monster and attaching your opponent's card to it as an Xyz Material. (Halving any damage your opponent takes for the rest of the turn is applied immediately upon resolving this effect.)
