The Competitive View
In the Stamina combination Guardian Kerbeus Knuckle Revolve/Orbit/Atomic, Knuckle's high Outward Weight Distribution bolsters Guardian Kerbeus's already-strong Stamina and adds Burst defense, with Revolve favoring more Stamina/Burst defense and Orbit/Atomic favoring Stability/KO defense instead; its small perimeter notches do give it noticeably less Life-After-Death than top Discs like 4/7 Glaive and Spread, however.
Verdict as the draft gives it: Once an excellent all-purpose Disc, Knuckle is now outclassed by heavier God Layer System Discs but remains viable for Stamina thanks to its Burst defense, making it a 'welcome addition' rather than must-have in Standard Format; in the Hasbro-Only Format (which lacks Left Spin and God Layer Discs) it is rated a must-have for all combination types.
- Circular shape with six small perimeter notches, four center holes, 'K' marking on prongs
