Notes & Combos
Starting combo should always be ASSD into Speeder. You can save ASSD effect if you feel that enemy has no negate.
Then summon AncientFairyDragon using Assault and Speeder. Special summon StardustTrail from deck using illumination (spell). Synchro summon Librarian. Then activate ASSD effect and Synchro Summon CrimsonDragon. Activate Assault graveyard effect to bring back ASSD. Synchro summon Dis pater and omega. Then baronne.
In perfect scenario, you will not need to activate stardust synchron graveyard effect to do the full combo.
The last synchro we want is Herald. It is so good because it makes our negates active when opponent activates Forbidden Droplet. You can summon it using level 3 libromancer geek boy or firestarter.
There will be times where you will summon Speeder using Herald and Jet. So you should not always activate Jet graveyard effect to get JunkServant.
If you are facing less Maxx C and more Labyrith, you can decrease Ash to 1 and add 2 Red Reboot. Likewise, if you are facing Kashtira a lot, you can add Dark Ruler No More or Evenly Match.
I will not list other post-Speeder combo because often, you will have to improvise depending on what card you have at hand and what effects were negated pre-Speeder.
