What battle problem is Merge meant to solve?
Merge is mainly used for a mix of movement, control and spin endurance. Final performance depends on the Blade, Ratchet, stadium and launch.

Balance
Start with Samurai Calibur 6-70 Merge; it is labelled as a official stock pairing with the note “Takara Tomy BX-45”. Compare it with Storm Spriggan 2-70 Merge while keeping the Blade, stadium, launch and opponent consistent.

Compare Merge directly with the Point 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.
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.
