Infinitrack Rank-Up Spell
(1) Machine Xyz Monsters you control cannot be targeted by an opponent’s card effect.
(2) Once per turn: You can target 1 “Infinitrack” Xyz Monster you control; Special Summon from your Extra Deck 1 Machine Xyz Monster that is 2 Ranks higher than that monster you control by using it as the Xyz Material. (This Special Summon is treated as an Xyz Summon, also transfer the materials to the Summoned monster.) You cannot Special Summon monsters, except EARTH Machine monsters, for the rest of the turn after you activated this effect.
this is in fact the card that Infinite Ignition Cancer Crane searches.
