- This card combos well with "Copycat" as this card's ATK will be increased by whatever ATK Copycat has.
- This card also works well with "The Calculator", whose ATK will be boostered by at least 2100 due to Junk Warrior's Level.
- Using the effect of "Relinquished" will not only get rid of an opponent's monster, but increase Junk Warrior's ATK as well.
- You can have "King of the Skull Servants" with multiple copies of "Skull Servant", "The Lady in Wight" and "King of the Skull Servants" in your Graveyard, to greatly increase ATK of "Junk Warrior".
- You can also use "DNA Surgery" (select Fiend-Type) and "Goblin King".
- "Chaos Necromancer" also works well with this card.
- Equip Demotion to a strong Level 3~4 monster or equip 2 Demotion on Junk Warrior to double it's ATK or other strong Level 5~6 like Cyber Dragon.
- This card combos well with "Nimble Momonga" and "Giant Germ". By setting it and having it destroyed, two more of that monster are Special Summoned. Then, during your next turn, summon "Junk Synchron" and revive the third, and offer them both, summoning Junk Warrior with at least 4300 ATK.
- If you have a Level 2 monster in your Graveyard already and Junk Warrior is on the field, use Angel Lift to Special Summon that Level 2 monster for Junk Warrior's effect.
- This card can become very powerful by summoning "Atlantean Pikeman" or "Clown Zombie" and then using "The League of Uniform Nomenclature" to summon two more.
