The first paragraph is mostly from Beyblade Wiki.
Quote:'''Weight:''' 18.2 grams
The Oval Disk, like the name implies, is shaped like an oval. 'O's appear on the upper side of the Disk as well for easy recognition. In theory, Oval would provide extra momentum to the Beyblade's spin by spreading the weight at two opposite sides. However, its underside is mostly hollowed out, making it the lightest Disk released. Its odd shape only ends up hindering the Beyblade's stability, making the customization using it precess dangerously the moment another Beyblade hits it. Even for niche combinations such as Hop Attackers using the Quake Driver, Oval only poses a risk of destabilization, and it cannot make up for it by any significant aid in attack.
==Overall==
This Disk is useless for all types of Beyblades and should never be considered in competitive play.
