- This card can be searched by "Diamond Core of Koa'ki Meiru", "Koa'ki Meiru Supplier", "Koa'ki Meiru Urnight", "Koa'ki Meiru Boulder", "Iron Core Specimen Lab", "Gear Gigant X", "Infinitrack River Stormer", "Clockwork Night", "Machina Metalcruncher", "Urgent Schedule", "Geargiauger", "Revolving Switchyard", "Machina Armored Unit", "Psychic Arsenal", "Heavy Armored Train Ironwolf", "BOXer", "Frontline Observer", "Summoner Monk", "Primathmech Alembertian", "Battle Royal Mode - Joining", "Vampire Dragon", "Resonator Engine", "Soul Rope", "Rescue Ferret", and other generic searchers.
- This card is good support in Gadget Deck since it relies on many defensive Trap Cards.
- This card can easily destroy most stalling monsters like "Krebons", "Spirit Reaper", "Arcana Force 0 - The Fool" and "Marshmallon" in battle.
- It can also stop flip effects such as "Gravekeeper's Spy", "Ryko, Lightsworn Hunter", "Dekoichi the Battlechanted Locomotive" and "Worms".
- You can increase this card's ATK to destroy "Ally of Justice Catastor" in battle.
- If "Jinzo" battles with this card, Traps can be activated and will resolve so you can play cards like "Mirror Force" to destroy "Jinzo".
- This card is an efficient way of destroying DARK or LIGHT monsters that increase their ATK due to their effect, like "The Wicked Avatar", "Chimeratech Overdragon", "King of the Skull Servants", "Tragoedia", etc.
- The trap card "Limiter Overload" can not only be used to satisfy "Powerhand's" maintenance cost, but can also activate its effect and Special Summon a "Speed Warrior" when it is sent from your hand to the graveyard. This can slightly help you against opponents who use hand destruction techniques.
- Use "DNA Transplant" or "Scroll of Bewitchment" to change monsters to DARK or LIGHT. "DNA Transplant" can be more effective, however.
- Reveal a normal trap card for the maintenance cost, then activate "Dust Tornado" if you need to set that trap.
