Signer

Ok, so this deck's goal is pretty simple. Summon all the signer dragons turn 1. Also, I put in a bunch of upgrades to the dragon, just in case you don't get the combo pieces, and synchron explorer for follow-up plays. You may switch out Synchron explorer, Life Stream dragon, Power tool braver dragon, (if you do, switch out Moon mirror shield) shooting star dragon, Accel synchron, Starlight Junction, Hot red dragon Archfiend abyss, Or phantasmal lord for any card(s) you wish.  Also, if you want, you may switch out scarlight red dragon archfiend for red dragon archfiend/ hot red dragon archfiend, blackfeather darkrage for black-winged dragon, or black rose moonlit dragon for black rose dragon, I just found them more useful in most situations. Here's the combo

Junk converter and any tuner+ any of the level 2s I put in the deck+ - All signer dragons.

First, your gonna wanna use junk converter to add junk synchron from the deck to hand, then normal summon it and use it's effect to special summon Junk converter from the graveyard. If you have Synchron carrier, normal summon that first. If you have caligo crow or Doppel warrior, special summon them. next, synchro summon junk speeder using junk synchron and the level 2 you special summoned In your extra monster zone, and special summon Stardust synchron, junk synchron, and assault synchron. Use Stardust Synchron's effect to add Stardust illumination from your deck to your hand, then use it to send stardust tail from your deck to your graveyard. next use assault warrior and junk speeder to synchro summon Black rose dragon, then use jet synchron to synchro summon black-winged Dragon using itself and Black rose dragon, in your extra monster zone. use jet Synchron's effect to add junk servant to your hand, then special summon it. Use stardust synchron and junk servant to synchro summon scarlight red dragon archfiend. Use stardust Synchron's effect to tribute scarlight red dragon archfiend and special summon itself. use assault warrior to special summon it back to the field and use stardust tail to special summon itself. use stardust synchron and stardust tail to synchro summon stardust dragon and use the stardust tails effect to special summon a token. Use junk converter and Junk synchron to summon Dark Dimension Soldier. Then use junk converters effect to special summon Junk synchron back from the graveyard. Activate Stardust illumination in your grave to banish it and increase the tokens level by one. Then use the token and Junk synchron to Synchro summon Garden Rose maiden. Use dark dimension's effect to special summon assault synchron from your banish zone, then use it to synchro summon Power tool dragon. Use power tool dragons effect to search Fleuret de fluer. Activate Fleuret to special summon assault synchron from your graveyard, then use that and garden rose maiden to synchro summon ancient pixie dragon. equip Fleuret to power tool. Then, use garden rose maidens effect to special summon black rose dragon from your graveyard,  therefore giving you all 6 signer dragons. IF you have junk servant in your hand at the start of the combo, do not use jet synchrons special ability to search it. instead, special summon it as normal, complete the combo up to before you use Living fossil, then use jet synchrons ability to special summon itself, use it to synchro summon Life Stream dragon using power tool dragon, then use Fleuret de fluer as normal and complete the combo. If you draw monster reborn, Living fossil. or Fleuret de fluer at the start of the combo, play the combo all the way until you add Fleuret from your deck to your hand,(if you already have it in your hand, add living fossil, if you already have living fossil, add Fleuret as normal) then use monster reborn/Living fossil to summon jet synchron from your graveyard, use it to synchro summon life force dragon, then proceed to finish the combo as normal. At the end of either combo, use black rose garden to +1 off of ancient pixie, plus pop 1 attack if it's the second turn, as well as weaken your opponents monsters on  next turn.

Junk Synchron + any lv 2 - 4 signer dragons

Synchro summon junk speeder, then special summon assault synchron, stardust synchron, junk synchron, and jet synchron. Use stardust synchron to search stardust illumination. activate the spell you searched to send stardust trail to the graveyard. Use assault synchron to synchro summon power tool dragon, then use it's effect to search living fossil. Then use jet synchron to synchro summon black-winged dragon or life stream dragon. search junk servant and special summon it. Use junk servant and stardust synchron to synchro summon scarlight red dragon archfiend tribute scarlight to summon Stardust synchron, then use stardust trail and assault synchron to summon scarlight and stardust trail from the grave. use stardust synchron and stardust trail to summon stardust dragon, then use stardust trail to summon a token. Banish stardust illumination to increase the tokens level by 1. then use both junk synchron and the token to synchro summon Dark dimension soldier. Use dark dimension soldier to summon assault synchron, then use assault synchron and dark dimension soldier to synchro-summon black rose or Ancient Pixie dragon. Instead, you could summon garden rose maiden,use living fossil to summon junk synchron, then use it and garden rose to summon black-winged dragon

IMPORTANT: If you draw stardust trail, everything is still ok. use the stardust illumination to send your second stardust synchron to the graveyard.
