Samurai Upper, ~22g.
Shares the same Metal Frame as Death Gargoyle MS' Circle Upper.
Simply put, Samurai Upper is Circle Upper with an extra gram or two (depending on what mold of Circle Upper is being compared) worth of plastic that may slightly help aid its Smash Attack.
Called Samurai Upper, but for some odd reason says "Samurai Edge" on its stickers. Personally, HMS already has many "Upper" ARs, "Edge" sounds a lot cooler and relevant.
This AR is just as much the Mack Daddy of HMS as Circle Upper is, and while the excess plastic may theoretically be worse for Stamina-oriented combos, or better for Attack, there is little in the way of measured, concise evidence supporting one AR over the other in any scenario. The final inductee to "The Big Three" of Attack ARs, completing the trifecta.
The two Upper's are interchangeable, and the Metal Frame itself is the definitive best AR of the series by a wide margin, with uses in every category.
Highly aggressive, capable of pulling off late-game knockouts almost regularly, to the point you may think it refuses to lose.
Incredibly solid weight distribution and innate survivability qualities making it a safe choice on any RC, which is an incredible feat.
Best Potential Combo:
AR: Samurai Upper (Either Spin, Same-Spin preferred)
WD: CWD Defense Ring
RC: Grip Flat Core (Ultimate Version)
Game Plan: Knock everything out without remorse and without much effort. Even late-game, expect Samurai Upper to have enough gas in the tank to knock things out, it simply isn't an AR you can count out at any point. Despite its frequency, it wouldn't be wise to rely on it, though, so make sure your launching is on point. Sliding/Catapult or Banking are the only ways to go with this combo, but if you get the hang of it, it feels like nothing can beat this combo. Just like Circle Upper, a case can be made for using an aggressive Bearing Core 2, as it doesn't have the exact same raw power, but is incredibly safe and similarly dangerous.
Battle Change Core, ~11g.
It may be easy to forget since most people only care about Samurai Upper when purchasing Samurai Changer, but this Beyblade is a part of the Gimmick Specialty series.
The RC's gimmick is mid-battle mode change. Unlike other iterations of this style of gimmick, BCC doesn't rely on RPM or manual alteration, but instead it changes via force applied to it. If you twist the upward slopes of the rather low CWD, you'll notice that a Semi-Flat tip extends and retracts. In battle, when hit in a certain way, BCC's slopes shift positions causing the tip to change between Semi-Flat and Hole-Flat.
In practice, this isn't a very competitively viable RC, as it has too much recoil to warrant high speeds, and not enough balance and survivability to warrant being stationary. The worst of both worlds, if you will.
Though not technically legal, you can unscrew the RC and put in a different CWD other than Samurai Changer's stock plastic CWD ring. You can also use the stock plastic CWD ring on regular CWDs, though with only one exception, the ramps must be facing down much like CWD Circle Attacker.
Stock, this RC is mostly not useful, but entertaining.
An interesting set up you can do is having two sets of God Rings or Reverse Defensers on this RC, one at the lower level after unscrewing, and one where the CWD is intended to be. It should be mentioned that when using alternative CWDs illegally, the mode change gimmick does not happen mid-battle so your tip remains consistent throughout. Unfortunately it isn't very useful, and while it is slightly difficult to knock out in some instances, the tip leaves a lot to be desired. Perhaps if it was wider or more balanced, such an illegal combo could be interesting. Or overpowered.
Best Potential Combo:
AR: Samurai Upper (Right-Spin)
WD: CWD Defense Ring
RC: Battle Change Core (Hole-Flat Start)
Game Plan: It feels like a bit of a cop-out to use the stock combo, but truthfully it is your best bet to win with this RC, let Samurai Upper or Circle Upper try to land a big blow and knock out the opponent, or die trying.
