New Weapon/Brave Series Opinions

These are all pretty good bases for button farming, with multiboost and stupidly high attack, and an SBR to boot. Only have 1 SB, but I think for where you want to use her for buttoning the teams should already have a high amount of SB anyways.
All of their awakenings consist of being unbindable, one SBR, one SB, a row heart, and a multiboost.

The skills look largely like Aizen's skill, with double orb change and an element flip, but they do not make on color orbs if used as a sub on teams, which makes the skill more useful while they are a leader.

Claíomh Solais

She will be the highest attack in the game with a multiboost. Should make buttoning Starden easier, and possibly even without having Grimmjow on both sides.

Skill: Water > Light, Dark > Heal. Change attribute to Light for 2 turns.
Wukong's skill, but without the heart enhance. 1 turn faster CD, so can be useful for any light teams if needed for SI.

Leader: Light Atk x 5, Fire Hp x 1.5. 1.5x Atk for 2 Light combos, 2x for 3+ Light combos
Having no preference for rows or TPAs means you can go in any direction. Largely, I can see an interesting pairing with Tifa or Ilmina for the enlarged board, and the added HP boost she provides will pair greatly. Ilm of course is a great sub, as well as any usual light power subs like Ariel, NY Kanna, or even split Hathor to utilize those 7c awakenings.

Grade: A

Arondight

Still impressive attack stats for a button base, and on color for Grimmjow inherit stat boost. Can also hold great water inherits like Isis or Orochi, if you really needed her typing or attribute coverage.

Skill: Fire > Light, Dark > Heal. Change attribute to Light for 2 turns.

A reverse DQXQ active. I guess you could combo this with a Gadius board if you wanted a more even split of orbs, or as a substitute for LAkechi/NYHanzo on a Saria board. 

Leader: Light 5x Attack, Water 1.5x HP. 2x Attack when 6+ connected Lights.

The leader skill definitely sounds like a row leader to me. You get access to A.DQXQ and L/B Apollo for orb changes, and A.Thor for a boost when considering light main attribute. For a water main attribute it doesn't look as good, since you will want to match light rows for your damage. You can skip water sub attribute if you don't want the HP boost, since the list of light/water row subs isn't the greatest. Raijin I guess is an ok but less than desirable sub, if you use her skill in conjunction with Arondight's for guaranteed 6 lights.

Grade: C

Caladbolg

A light cross leader that uses wood sub attribute for health. It is almost like playing a light version of Aizen, trading an RCV multiplier for an HP multiplier. Also, lowest attack of the series (but still high compared to everything else)

Skill: Water > Light, Fire > Heart. Change attribute to Light for 2 turns.

Pairs with Superman for a light favorable bicolor. Otherwise, only competes with Baal and Wukong for a water > light convert and DQXQ in light attribute for fire > heart. If you don't have them, this kind of orb convert is useful.

Leader: 5x Atk to Light, 1.5x HP to wood. 2x Atk for each light cross.

So many similarities to Aizen, but is only a 25x unconditional compared to 36x. You get access to Valkyrie(Ana and chibi as well), and Awoken Apollo for orb changers. You can also sub Athena Another if you have it, or regular Athena, and even Momiji is surprisingly decent here. NY Spica also can be pretty useful to cover SBR and create a column of lights for a guaranteed cross. Awoken Amaterasu and Awoken Indra give Caladbolg easy access to great utility as well. Could make an interesting pairing with Odindra to cover the low RCV, or Ma Chao for a 7x6 and RCV.

Grade: B

Gan Jiang and Mo Ye

I love me some dark row leads. However, the light/dark sub pool isn't the greatest, but if don't mind losing the HP multiplier you get access to really good row subs. On typing for Juza for buttons.

Skill: Water > Dark, Wood > Heal. Change attribute to Dark for 2 turns.

Water to dark is pretty rare, shared by Satsuki and Henry from the Pad Tourney collab series. Can pair with Karin's or Ryune's board for a dark heavy bicolor with hearts.

Leader: 5x Atk to Dark, 1.5x HP to Light. 2x Attack for 6+ connected Darks.
You get access to FA Luci, Escha, Castor, and Lead Akechi as pretty good subs. Sheena is an oncolor bicolor change you could use as a sub, or as a quality inherit. Otherwise, Dark has an abundance of row subs if you don't want the HP multiplier, and you could tap into the TPA side for the unconditional 25x with Sub Satsuki or DKanna. You could also use Dill Sirius system for old school style Shivadra farming, but its 2017. Can also pair with Diao Chan for 7x6 and RCV.

Grade: B

Mysteltainn(?)

Wood and dark funsies. I can see Revo Meimei system being really interesting here, with Gronia board being amazing. Also, the next highest attack with multiboost behind Claíomh Solais, and on typing for Vritra inherit for buttoning.

Skill: Fire > Wood, Light > Heart. Change attribute to Wood for 2 turns.

Fire to wood is decent, and can pair with Leilan or Zuoh/Romia for a wood heavy board. Losing fire/light means it misses out on being excellent for wood cross leads like Acala and Odindra, but its a pretty decent orb change to have.

Leader: 5x Atk to Wood, 1.5 HP to dark. 1.5x Atk for 2 Wood combos, 2x for 3+ Wood combos

I can see a potential in pairing with Romia for a 7x6, but it won't be as strong as Claíomh Solais pairing with Tifa or Ilmina. Revo Meimei system is definitely considered here for funsies. Aside from Meimei, you get Sub Ishida, Gronia, Ruel, Romia, Lead Spica, Ragdra, and Revo Astaroth for noticeable on color subs. A. Freyja, Revo Ceres, and Revo Susano supply decent utility to be considered for base subs as well.

Grade: A

Kind of an interesting series, but should be great for both button farming and as interesting leaders for mid to endgame.
