Juno-Seto is a worthy arena leader for a multitude of things.

On the topic of LS:


 * Def-ignore negation: Potentially a Mifune-counter, though not by a long mile.
 * 20% chance of an Angel Idol: Which you can go for the same thing with Limera.
 * 4-7 BB fill rate when hit: This one is important, because when coupling with the Angel Idol effect in arena, most units may have their BB filled, so on a defense team in Colos, that enables someone to pop their BB out, which is usually enough to severely cripple their whole team.

On the topic of BB/SBB:
 * Barrier + mitigation is a way to go with defending the enemy attacks, and sometimes it can even counter the hefty amount of damages from BB.
 * HoT is extremely potent when combined with her Rec boost on LS.
 * Revive ability on her SBB is the selling point. I've faced a Juno-Seto team and ultimately lost when she pops out her SBB and revived 2 units. Couple this with her Angel Idol LS and it's really frustrating when enemy units just kept on reviving when my ally team here is like nope a Mifune or Azurai is a death sentence for me

On the topic of SP:
 * 2-turn mitigation is kind of a nightmare for the enemy team
 * Rec>Def boost, again, works well with her LS. Now bring maybe a def and/or rec booster unit and the colos team can be invincible.

On the topic of less useful SP for arena/colos imo:
 * BB reduction could help her with getting more SBB.
 * BC/HC drop rate is also a good rejuvenator move if you're desperate enough.
 * Negation of status ailments is, again, the ultimate anti-debuffer.

Her kit is a massive combo game of arena. She is capable of keeping units alive that much. Don't underestimate her in the arena game.
