0-70 uses 0 main contact points and a 70 height class. Lower setups generally expose less underside, while the complete Blade, Bit and launch determine the result.

Balance
Start with Ghost Circle 0-70 Free Ball; it is labelled as a reported tournament alternative with the note “9% of recorded podium builds · all-time”. Compare it with Shinobi Shadow 0-70 Bound Spike while keeping the Blade, stadium, launch and opponent consistent.

0-70 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 0-70 directly with the 0-60 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.
