Which complete Under Flat combo should I test first?
Start with Shark Scale 4-50 Under Flat; it is labelled as a official stock pairing with the note “Takara Tomy UX-15”. There is no second verified build yet, so do not invent one just to fill a deck.
How much recent tournament evidence is there for Under Flat?
Under Flat does not appear in the 20 recent winning decks reviewed by BeyXBuild. That does not make it unusable; it means the site should not call it a tournament-proven staple yet.
BATTLE PURPOSE
What does Under Flat change?
Under Flat is mainly used for aggressive movement and early knockout pressure. Final performance depends on the Blade, Ratchet, stadium and launch.
Treat this as a testable starting point, not a win guarantee. The Blade, other parts, stadium and launch can change the result.

FAQ
Under Flat frequently asked questions
What should I compare Under Flat against?
Compare Under Flat directly with the Rush Bit in the same complete build. Run at least five launches per side and record knockouts, bursts, self-knockouts, scraping and spin finishes; change only this one part.
What result means Under Flat should leave my three-Bey deck?
Drop it if the extra movement produces more self-knockouts and early spin loss than clean knockouts. Record those outcomes separately over repeated launches.
