Though this obviously is useful against opponent's monsters, you can equip this card to your own Machine Monster and use "Machine Duplication" to summon two more at full attack.
Combine this tactic with Equip Shot to inflict massive damage.
Use this card in tandem with Mist Body (or any monster that is not destroyed by battle) whilst your opponent's monster is in Attack Position to get a nearly direct line to their life points.
This can help use the effects of monsters whose effects only activate when they destroy a monster by battle, such as "Fenrir", "Hydrogeddon", "Timeater", or Inferno. This is especially true for low-ATK monsters under this category, or when opposing a monster with overwhelmingly high ATK (ex. 4000).
