Directly Synchro Summon Level 6 Synchro Monsters ("Synchron Explorer" negates the Level-reducing of "Road Synchron" because this effect is applied when a Synchro Summon is declared with a monster other than "Road Warrior").
Add "Quillbolt Hedgehog" or another level 2 monster to Synchro Summon "Road Warrior".
Directly Synchro Summon "Nitro Warrior", "Junk Archer" or "Junk Berserker". (the effect of "Quickdraw" of substituting a "Synchron" monster, and only being able to Synchro Summon a Synchro Monster that requires a "Synchron" Tuner are not considered effects, so they will not be negated.)
This card's effect can be more useful than "Necro Linker", especially for "Formula Synchron".
Use "Foolish Burial" on a "Synchron" monster so that it can be revived with "Synchron Explorer".
Many Synchro Monsters can easily be Summoned by using this card effect to revive a "Quickdraw Synchron" in the Graveyard, playing "Inferno Reckless Summon" to Summon two more "Quickdraw", and having "Level Eater" in the Graveyard, lowering the Level of "Quickdraw" to Special Summon it.
A typical Synchro combo, is to first discard "Dandylion" to Summon "Quickdraw Synchron", producing 2 "Fluff Tokens". Tune them for a Level 6 or 7 Synchro (like "Junk Archer"). Finally, play "Syncron Explorer" to bring back "Quickdraw", and then tune them together for another Level 6 or 7 Synchro Monster (if there still is a "Fluff Token", they can be tuned for "Junk Destroyer" or "Road Warrior").
