What battle problem is 4-55 meant to solve?
4-55 uses 4 main contact points and a 55 height class. Lower setups generally expose less underside, while the complete Blade, Bit and launch determine the result.

Balance
Start with Clock Mirage 4-55 Under Needle; it is labelled as a recent top-cut build with the note “20% of this Blade’s recent podium builds”. Compare it with Clock Mirage 4-55 Low Orb while keeping the Blade, stadium, launch and opponent consistent.

4-55 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.

Compare 4-55 directly with the 4-50 Ratchet 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.
Drop it if it does not beat a specialist in any matchup your other two Beys leave open. Flexibility only matters when it covers a real deck weakness.
