Deskbot

"Deskbot", known as "Bunborg" (ブンボーグ Bunbōgu) in the Japanese version, is an archetype of EARTH Machine-Type monsters. They are low-Leveled monsters that support Machine-Type monsters in general, with a swarm strategy and effects that increase their ATK and DEF.

Playing style
As mentioned above, "Deskbot" monsters can swarm and boost ATK easily. "Deskbot 001" boosts its own ATK and can special summon itself from the graveyard; "Deskbot 002" boosts your other Machine-Type monsters' ATK and DEF, and can add "Deskbot" cards from the deck to the hand; and "Deskbot 003" special summons a "Deskbot" from the deck upon normal summon, along with being able to grant a boost to a "Deskbot" once per turn.

With all this in mind, it's clear that the "Deskbot" strategy is geared toward large swarms leading to OTKs. They can make use of excellent Machine support cards like "Machine Duplication" and "Limiter Removal", as well as other swarm cards like "Inferno Reckless Summon" and other ATK-boosters like "Solidarity" or "United We Stand". Meanwhile, they can also use "Deskbot 001" to perform Synchro Summons, since it's a Tuner monster.
