Get Grinding, Get Krawling
The most annoying underdog deck
---
Pure Krawler using Small World package (all thought up by yours truly (sucks))
You can use small world to bridge from any monster to any monster (exceot gadarla) by using vernusylph as the bridge. If you need kaiju-level removal then you can bridge from any monster to gadarla using cataclysmic as the bridge. Vernusylph is a decent card you don't mind drawing while cataclysmic while easily summonable, sucks so you'd rather not draw him.
Girsu is a one-card starter. Normal summon girsu -> send Mind Meld from deck -> activate girsu effect to make token -> link away him and the token for Lib -> activate Lib effect to set Pawns from deck -> use Mind Meld gy effect to summon The Great Grind King, Deus X from deck face-down to Lib's arrow.
During your opponent's turn you can use pawns to flip up Deus X and he will floodgate all of your opponents monster effects activated on the field (extremely infuriating) then the grand grindgame can begin.
The goal is to have Deus X sit on his fat royal disc-behind as you accrue value and eventually an army of 5 krawlers and the great commander and tactician, Qualiark. At which point, because you have 6 krawlers Qualiark lets you attack directly and your opponent is unable to activate anything during the battle phase so basically you get to swing out in a blaze of glory. That or your opponent rage quits. Keep Deus X alive by boosting his def with In Shadow, revive him with the Krawler links and Glial, and if you know your opponent has targeted removal froms spells/traps you can use pawns to flip him facedown (he can negate effects that target him facedown and flip back up).
Dark ruler no more is necessary because the deck is woefully unprepared for going second and Borreload is just funny so..
