Infinitrack Road Roller →Used Deck

(1) The Special Summon effect from the hand/GY can be triggered by the release/removal of some "Infinitrack" monster effects with the "Infinitrack" Deck, so I think it's easy to meet the conditions.
Due to the effect of (2), if there is a "Machine" X monster that uses this card as an X material, all of the opponent's monsters will lower his Defense Position and DEF, so it can be used to limit attacks and assist in battle destruction. But I think it's excellent.

Infinitrack Min: "I want to be strengthened..."
Konmai: "It's a Road Roller!!"
Infinitrack People "Oraoraora (I don't need this kind of enhancement)"
Konmai: "It's late! It's impossible to escape! Waste waste waste!"
Konmai "The 11th term has passed! Uriaaaaaaaaaaaaaaaaaaaaaaaaaaaaa (environment)"

A level 5 ground machine that will be the new deployment member of the Infinitrack.
Has the ability to make himself his Special Summon in response to Earth Machine's release or face-up elimination when present in hand or in her GY.
All his level 5 Infinitrack monsters other than this monster have a self-SS effect that activates by releasing Earth Machines on the field, and many of them are activated by excluding themselves, which are Earth Machines, from his GY. It is easy to satisfy the condition because it has the effect of
The Infinitrack X members also have the ability to release and revive Machine Links such as Goliath, so you can pull the trigger there as well.
With this effect, if he leaves the field after Special Summoning, he will be removed, but if it is a rank 5X material, it will be possible to continue his Special Summon from GY regardless of that.
Since Brutal does not impose restrictions on his Special Summon after activation, it would be good to connect to his Machine X monsters other than EARTH, such as Nova Infinity.
He also has the ability to give a permanent effect to a Machine X monster by becoming an X material for that monster, which makes all the monsters on the opponent's field become his Defense Position and also lowers their defense power.
Whether or not this is an effective suppression depends largely on the opponent's Deck, and if Machine X leaves the field with this monster as an X material due to an effect in the middle of development, that's it, so I think there are many cases where it's only a small thing. However, it will definitely be useful to support the battle destruction triggering X materialization effect that the members of Infinitrack X have.
