Fan favorite Generaider forged with Orcust and World Legacy making it competitive, fun, and fresh with new gameplan and interaction. Best card is Girsu, not only it can start your full combo, it is an Orcust piece too which means very useful in the grind game. I will explain full Lib combo with Girsu (1 card combo).
For the Lib combo, you normal summon Girsu, dump World Armor, activate Girsu ss token, link off token for Linkuriboh, ss Lib (using Linkuriboh, important), activate Lib search Succession, activate Succession ss World Armor, activate World Armor add Monsrtosity, link Lib off for Linkross, activate Linkross (chain Lib if you want to spin opponent's card) ss 2 tokens, ss Linkuriboh from GY using token, ss fusion Trishula (using token, Linkuriboh, and World Armor), activate Monstrosity (ss 2 lv9 from deck or 1 lv9 from hand) ss Mardel and Dovelgus, activate Mardel add Genereaider Boss Stage, activate Dovelgus ss Orcust from hand, overlay 2 lv9 for True King of All Calamities, and proceed with your Orcust combo (using Linkross and Orcust you just ss before).
The Orcust combo ceiling is low without Harp (basically revolves around Orcust Knightmare, dump Wand, activate Wand ss Knightmare from banished pile; Brass ss Orcust from hand; Cymbal ss Orcust from GY), so dont expect much. During opponent's draw phase, Stage can be activated in response to opponent's normal draw, ss Hoarr along with Generaider tokens (fodder for Hoarr or I:P).
Card synergies: Hoarr (dark for Allure, lv9 for Monstrosity), Mardel (searches Stage, lv9), Dovelgus (ss Orcust from hand, lv9), 2 Wand + 2 World Armor (just in case it's drawn, combo pieces, World Legacy fodder for Orcustrated Return, dark for Allure, dumped Wand can ss Armor from hand), 1 Cymbal, 1 Brass (if Cymbal is drawn, you can dump this and ss Cymbal from hand, essentially acting like a second Cymbal while can summon other Orcust from hand too), and the staples like handtraps + s/t removal + generic draw cards.
Extra deck: Combo pieces (including Orcust), I:P + Topologic/Knightmare (can be used with Generaider tokens), and other rank 9 target (Enterblathnir or Infinitrack). It is hard to make Borrelsword, so you can replace it with other generic if you want.
Side deck: Matchup specific.
Cards to think of: Scrap combo (good one, but needs more space and we already choose Lib combo), Unchained Abomination (or all other great I:P target; extra deck is too tight, you have to replace something to include this, applies to other generic extra deck monsters too), Gizmek Orochi (resource is important, so the banishing cost is too big of price to pay; can be played depends on you), your suggestion cards go here.

Expected 1st turn: (with Crescendo set)
Pros: Great first turn board, possible disruptions (I:P to Unicorn or Topologic), possible negations (Crescendo, True King of All Calamities, Hoarr), Orcust recursion and protection, big bodies, sometimes can play through handtraps, lots of handtraps for going second, and easy OTK.
Cons: Board can be shut down using strong cards like Super Poly etc (but Calamities effect will still linger even after being outed, so another pros), drawing the lv9 Generaider sucks sometimes.
PS: Shoutout to
Lithium2300 for the Lib combo.
