If you could +10 any 5* exclusive, who would it be?

I would choose my (+Atk -Hp) OG Lucina
Falchion
Reposition
Aether
Distant Counter
Wrath 3
Even Speed Wave / Odd Attack Wave
Heavy Blade

I don't think I'll be seeing this anytime soon though. It's been 8 months and I still haven't gotten another Lucy :'(

Mine would be Ryoma.

Raijinto
Draw Back
Bonfire
Steady Breath
Vantage 3
Hone Atk 3
Brash Assault 3

W!Lissa.Don't know the Build but i know who

Veronica

I know she's not an available unit just yet, but based off this picture she's going to be a powerhouse greater than Hector!

Fjrom I currently have her with +atk -hp ivs at +2, but it's just so hard to get her since she is so limited and I don't have orbs to keep trying for her when I end up with one of the other blue units.

Luthier

I know he's not in Heroes yet, let me dream.

Either Ryoma or Ninian:

Ryoma (+Atk / -Res or +Spd / -Res)
Raijinto
Reposition
Moonbow / Glimmer / Miracle
Life and Death 3
Vantage 3
Def Smoke 3
Distant Def 3 / Atk +3 / HP+4/Atk+2

Ninian (+Spd / -HP)
Lightning Breath+ (Spd-refine)
Dance
Aether / Bonfire / Iceberg
Steady Breath
Guard 3
Atk Smoke 3 / Spd Smoke 3
Quick Riposte 3

I would like to choose Dorcas

Dorcas +Res/-Hp

Default Weapon
Reposition
Iceberg
Warding Breath
Chill Atk
Odd Res Wave
QR

Seth
the man needs some love

My boi Jaffar, i got him but he is only +1, i hope he gets demoted someday.
With Deathly Dagger Eff
Reposition
Moonbow
Close Counter
Vantage
Savage Blow
Savage Blow

My Deirdre. She was my first 5* and I hold her dearly in my heart because of that. She's my best Dragon Emblem check and can even deal with Tikis (a bit harder to deal with a buffed M!Grima tho). She was my Summoner support for the longest.

I would choose a (+spd/-res) Ayra
Ayra Blade
Reposition
Regnal Astra
Brazen Atk/Spd 3
Desperation 3
Odd atk wave 3
Spd smoke 3

Easily Mia for me. She's one of my top 3 favorite characters in the series, alongside Fir who's my only +10 and Larcei who isn't in Heroes yet sadly. And yeah all 3 of those favorites are female swordmasters, I have a bit of a bias in that regard.

I'd say L!Ike due to bias but he's fairly easy to get in Legendary banners so I'll say either Micaiah or Summer Gaius. I love both of them character-wise and as units. Plus, I could use better IVs for both of them (they're +spd, -res and +atk, -spd respectively).

Either Hector (because I love him from his original game) or Ishtar.
