Combination fo Speedroid and Libromancer, "Libroidmancer" if you will. Originally concieved in the legend anthology event.
Note that this list was made for Master Duel June 2023.
The theory behind the deck is that the archetypes are bridged by Libromancer Geek Boy and Hi-Speedroid Rubber Band Shooter.
Rubberband Shooter requires any 2 WIND monster for link material. Libromancers don't use their normal summon, so you can do your Libromancer plays saving the geek boy, then normal summon a wind monster from hand and make Rubberband Shooter for speedroid synchro plays.
It rounds out Speedroid by giving it an omni negate other than Baronne de Fleur , Libromancer Displaced gives it a monster steal, and Libromancer Fireburst helps with OTKs.
You can't make Crystal Clear Wing Synchro Dragon on the same turn as Libromancer plays because the Hi-Speedroid Cork Shooter can't use its effects if you special summoned non-wind monsters.If you only opened speedroid cards then getting out Speedroid Terrortop is a one card combo into Cystal Clear Wing Synchro Dragon (search taketomborg, summon red-eyed dice from deck to make cork shooter, special summon both, make clear wing then cystral clear wing).
Use whatever staples you see fit, I won't go into too much detail but bystials are good synchro or ritual material. The following is explanations for the engine:
Libromancer Geek Boy - Wind, searches field spell or continuous spell.
Libromancer Fire - search any libromaner monster
Libromancer Agent - Lv6 for synchro and add a libromancer back from the GY. Search after using intervention.
Libromancer Doombroker - Priority target to get out, make sure you activate its effect as soon as you summon it or you may get locked out of its effects. Also attacks directly then bounces.
Libromancer Fireburst - distant 2nd best, but it very helpful for getting lethal, deal double battle damage and has 2 monster attacks. Search from intervention
Libromancer Intervention - omni negate (does not destroy) that recycles your libromancer plays. Summon Libromancer fire and figure determine whats best to search.
Libromancer Displaced - steal a monster, does not recycle resources, but does NOT require a ritual. If you used a ritual, keep the monster, if not, return it to HAND during the end phase. Intervention is the priority, but its a good draw in the opening hand.
Libromancer First Appearance - ROTA field spell thats also the ritual spell, not you can only activate one of the field per turn and getting destroyed will end your libromancer plays for the turn.
Libromancer Realized - underrated inclusion, lets you use libromancer as synchro materials instead of ritual materias. If you opened with First Appearance search this instead, but its too bricky to play at more than 1.
Speedroid Double Yoyo - this and terrortop are the best search from Rubberband Shooter, but maybe only play 1
Speedroid Terrortop - Does not lock you into anything and search any of your speedroid, is only limited because its a genereic rank 3 engine :(
Speedroid Den-Den Daiko Duke - play at 1, good to get into GY.
Speedroid Fuki-Modoshi Piper -godly level 4 tuner that gives you extra resources for free.
Speedroid CarTurbo - free special summon. LOCKS into wind monster EFFECTS
Speedroid Taketomborg - godly free special summon and special summon from deck. Special summoning from the deck LOCKS into WIND SPECIAL SUMMONS.
Speedroid Marble Machine - normal summon searchs a speedroid, one card into rubberband shooter. LOCK into WIND SPECIAL SUMMONS
Speedroid Red-Eyed Dice - necessary for Cystral Clear Wing Synchro Dragon, can also make lv7 and lower synchros.
Speed Recovery - monster reborn without a hard once per turn and adds a speedroid back to hand the next turn. play 3
Extra Deck
Hi-Speedroid Rubber Band Shooter - god tier legacy support, search, foolish burial, and extra normal summon. Normal summon LOCKS into synchros but we only play synchros so it doesn't matter that much.
Hi-Speedroid Cork Shooter - makes Crystal Clear Wing
Hi-Speedroid Hagoita - good for some combos, can you use GY effect every turn, also can interrupt xyz plays which is funny.
Stardust Charge Warrior - best lv6 we can work with, can use for your destiny draw moments.
Wind Pegasus @Ignister - 3rd best lv7, usually banish with Rubberband Shooter but its worth for backrow decks and has a good GY effect.
Clear Wing Synchro Dragon - did you know this card has 2 negates
Clear Wing Fast Dragon - requires WIND NON-TUNER. Depends on the match up for which is better but can usually make both clear wings on the same turn.
Stardust Dragon - only playing because its the best wind lv8 because this deck has not lv2 tuners for Accel Synchro Stardust Dragon but is still useful for stuff lightning storm
Crystal Wing Synchro Dragon - actual best lv8 but need a synchro non-tuner. I make it less often than I thought I would.
Hi-Speedroid Kitedrake - WIND MACHINE Tuner so you can use Libromancer fire+ Fuki Modoshi Piper. Extremely good for turn 2 and 3, people don't know about it because of its summon requirements. If its effect resoves you probably win the game. Floats into speedroid search
Stellar Wind Wolfrayet - tied with Shen Shen for best lv9, swap with it depending on the meta.
Baronne de Fleur - its baronne.
Crystal Clear Wing Synchro Dragon - underrated boss monster. its a semi tower and spell negate, the current meta usually has trouble dealing with it, also floats into any wind search.
Hi-Speedroid Clear Wing Rider - reqires any wind synchro, not just clear wing. Destoys a bunch of cards and gains a bunch of attacks, and it even has a summon animation. During your opponents main phase it tributes itself to summon clear wing and fast dragon (and pegasus) from the extra deck so its worth considering to go into turn 1.
Side deck is extra cards worth considering (or not considering):
Harpie's Pet Dragon - Fearsome Fire Blast and Speedroid Rubberband Plane - free higher lv special summons
Libromancer Magigirl and Libromancer Mystigirl - gives extra body and extra negate, but you can only search so many libromancer cards so I wouldn't bother.
Cynet Mining - searches Libromancer Fire
Mecha Phantom Beast O-Lion - wind with gives a free token, but isnt searchable
Clear Wing Synchro Dragon - consider a 2nd copy of it because of clear wing rider's 2nd effect and being able to hang on to wind pegasus
Virtual World Kyubi - Shenshen - use instead of Stellar Wind Wolfrayet depending on the meta (or use both maybe?)
Speedroid Wheel - better in a pure speedroid build but I don't like the resource cost in this deck.
Terraforming - currently banned in MD because they were huffing paint thinner, instant include when unbanned.
Pre-Preparation of Rites with Libromancer Bonded and Libromancer Firestarter - pre prep can go + 1 and with an extra ritual search but its a dead card if you drew fireburst or bonded so I wouldn't consider it outside a pure lbromancer build.
Speedroid Dupligate - decent card but it's too bricky for my taste when the 2nd engine only has one wind monster.
