You can Synchro Summon this card by Normal Summoning "Junk Synchron", and use its effect to Special Summon a Level 1 monster from your Graveyard. Then, activate "Level Retuner", reducing the Level of "Junk" by 2.
Since this monster is LIGHTAttribute, you can use "Sunny Pixie" with any Level 1 non-Tuner to Synchro Summon this card and gain 1000 LP.
Far from being limited to merely Accel Synchro Summoning, this card is capable of Synchro Summoning any monster for which it can be a viable Tuner (ie. where a specific Tuner is not required).
Based on its card effect, you can also use this as a regular Tuner to "Accel Synchro" any regular Synchro Monsters during your opponent's turn aside for "Shooting Star Dragon" (similar to the basic "Urgent Tuning").
The easier path to Synchro Summon this card is to discard "Fabled Lurrie" for the cost of "The Fabled Chawa". Because of the effect of "Lurrie", you have to Special Summon it on the field, having instantly a Level 1 monster and a Level 1 Tuner monster in order to Synchron Summon "Formula Synchron". Because there are a lot of ways of having a "Stardust Dragon", therefore, you can Summon "Shooting Star Dragon".
You can use the previous trick and activate "Torrential Tribute", then, as an answer, chain a "Starlight Road". It will destroy at least 2 monsters (fulfilling this card's requirements). You'll keep "Lurrie" and "Chawa" but you'll also have a "Stardust" on the field, then Synchro Summon.
Use "Fires of Doomsday" during your opponent's turn to get a Level 1 monster on the field easily. You can also use "Natural Tune" to make one of the Tokens a Tuner.
Use "Reinforce Truth" to Summon "Attack Gainer" from your Deck. Then Summon a Level 1 monster from your hand and tune. This method is also easy to use in a Deck based on Summoning "Stardust Dragon" as well.
You can use this card to Synchro Summon "Black Rose Dragon" during your opponent's turn to clear the field and possibly a field advantage during your turn. Note that the effect the Synchro Summon must be Chain Link 1, otherwise "Black Rose" will miss the timing.
Another simple way to Summon this card is to Summon "Treeborn Frog" from your Graveyard via it's effect allowing you to Summon "Fishborg Blaster" from your Graveyard by discarding a card.
Also Summon "Cyber Shark" to be ready to Synchro Summon a "Black Rose Dragon" on your opponent's turn at the end of their Main Phase 1.
Activate the effect of "Scrap Mind Reader" and destroy a face-up "Scrap" monster to Special Summon it. Then activate "Scrap Searcher" upon the destruction of the selected "Scrap". You can then Synchro Summon this card. Be warned if you have any non-"Scrap" monsters on the field, "Searcher" will destroy them.
Use this card's effect to Synchro Summon during your opponent's turn in tandem with "Synchro Material" against an opponent's "Stardust Dragon", allowing you to use both monsters to Synchro Summon a "Shooting Star Dragon" under your control on your opponent's turn. This also bypasses the drawback of "Synchro Material" disabling your Battle Phase for the turn you would have Synchro Summoned, keeping your Battle Phase open for your next turn.
A rare and hard drawing combo is: The effect of "Buten" to "Tuningware" ("DNA Surgery" choosing Fairy-Type) and tune with "Darksea Rescue" Synchro Summon "Formula Synchron"; this makes you draw 3 cards. "De-Synchroize", "Formula" and repeat the process (assuming the effect of "DNA Surgery" is active and on field while choosing Fairy-Type and another "Buten"); thus draw 3 more. Drew a total of 6 cards. You'll have a total of 9 drown cards by these effects if you have all three "Buten" in the grave, activate another "De-Synchro", and repeat with the above situation.
Drawing 9 cards from this combo require 2 "De-Synchros", "DNA Surgery" and three "Butens".
This card can be used for the Synchro Summon of "Shooting Quasar Dragon". One way is by simply tuning this card with two Level 5 Synchro Monsters.
In a "KarakuriMachinaPlant" Deck, you can Summon this easily to help you quickly Summon "Shooting Star Dragon". On your fist turn play "Foolish Burial", send "Dandylion" to the Graveyard to Special Summon two "Fluff Tokens". Summon "Lonefire Blossom" play the effect and Summon "Glow-Up Bulb" or use "One for One", or just Summon normally if you already have it in your hand. Tune with one of the Tokens to Summon "Formula Synchron" and draw a card. Special Summon "Machina Fortress" from your hand and Summon "Glow-Up Bulb" from the Graveyard with its effect, tune them together to Summon "Stardust Dragon" Synchro again for "Shooting Star Dragon". The leftover Token will help you out with some extra combos depending on what cards you have left in your hand. Try to see if you can Summon a "Shogun" Synchro first before you try this combo as it will be deadlier on your opening turn against your opponent.
It is very easy to be Synchro Summoned by using "One for One". Discard "Glow-Up Bulb", then Special Summon "Tuningware", use the effect of "Glow-Up" to Special Summon itself. Then Synchro Summon "Formula Synchron". In addition, you can draw 2 cards.
In a "Quickdraw Dandywarrior" Deck, use "One for One" to send "Dandylion" to the Graveyard, and Special Summon any Level 1 Tuner from your Deck, such as "Glow-up", "Spore" or "Copy Plant". Then tune your Level 1 Tuner to one of the "Fluff Tokens" and Synchro Summon this card.
You can then Summon "Debris Dragon" to Special Summon "Dandylion" from your Graveyard, and then tune "Dandylion" and a "Fluff Token" to "Debris" to Synchro Summon "Stardust Dragon". This prepares the field for the Summoning of "Shooting Star Dragon"'.
Alternatively, you can swap "Big One Warrior" for "One for One". Use the effect of "Big One" to discard "Glow-Up" from your hand and Special Summon "Big One". Then Special Summon "Glow-Up" from your Graveyard and Synchro Summon this card.
