A team to beat Lucina GHB?

Reinhardt, Brave Lyn, 2 Wings of Mercy Dancer/Singers.

I beat it with these units
Adul tiki +10 LB (res), Aether, WB, QR2, Atk smoke 3, CD 3
Shenna +7 Slay axe (res), Aether, DC, VF, hone armors, atk Ploy 3
Genny +0 Razzle Dazzle, atk 3, savage blow 3, def tactic 3
Lute, OG set with desperation and res tactic 3.

I just bait in the first turn with tiki in the left and shenna in the right, in the second turn lucy went for shenna and died instantly, was prety easy.

I beat it with a F2P-ish team:

Adult Tiki: +Def Lightning Breath, Reposition, Bonfire, Brazen Atk/Def, Quick Riposte, Spur Atk, Distant Defense. She basically soloed the left side of the map.

Nino: Fury blade set with Drive Atk. Fought a red mage early to activate Desperation, spent the rest of the battle cleaning up ranged units.

Eirika: +Eff Sieglinde, Reposition, Moonbow, Swift Sparrow, Bowbreaker, Hone Spd, Fortify Res. Buffs and Repositions, plus a couple kills. Swift Sparrow and Bowbreaker aren't necessary, I just have them on her because I use her in arena.

Shiro: Bright Naginata, Reposition, Bonfire, Steady Stance, Quick Riposte, Drive Spd, Attack +3. Baited and killed the two brave weapon users with buffs from Eirika and Nino, then hung back and Repositioned teammates around. If you don't have Shiro, you can try Nowi, F Corrin, or Lukas.

When I fought her she never actually used Future Vision.

Used my tactic team
L!Lyn with vanilla set + iceberg
Barblade Linde
S!Cordelia w/Galeforce and heavy blade SS
Flier Olivia

Had olivia tank the red mage/axe cav turn 1, L!Lyn kill the brave lance solider on the right, then repositioned Lyn out with Cordelia and had her tank the bravesword cav

I didn't even give her a chance to use it not once with my team.

If you are still curious, I managed it with a Horse Emblem team consisting of Xander, Elise, LA!Lilina (Gronnblade+), and LA!Roy (Brave Bow+). I don't think the exact units matter, but at least a Gronnblade and Brave Bow (don't need the 5-Star versions), a Red tank, and a Healer are really good for clearing the map.

I had it set up such that my Lucina had no choice but to initiate against my Lilina, which meant eating a fully buffed and Glimmer-powered Gronnblade. Suffice to say, that was probably the most entertaining part of the battle for me.

[Double post]

I ended up having to beat it with Rein and Blyn and 2 dancers/singers. The only reasons I won was because I gave Pazura the Spur Atk seal and she survived Legendary Luci's attack with one health left. ONE! EVEN WITH TRIANGLE ADEPT!

For Infernal:

Strong red sword with DC and Aether can solo much of the left side; so heroes like Ayra or Soleil. I have a +10 Ayra that can do this. Her skills in addition to the above is Renewal, Attack Smoke, Repo.

Strong green such as Nino to take out the blue units. Again, +10. Fury set with Repo.

A blue unit to take care of the red horse cav with brave sword on the right side. For me it was Lancina. Full support with double drives, Fury, Renewal, Repo.

A dancer (Lene for me) to help retreat when Bowcina starts moving. In this case I retreated to the lower right and killed her with Nino. Fury, Hone Attack, Firestorm Dance.

Horse Emblem (F2P) will do just fine. My team is like this:

- Siegbert +1 (+Atk/-Def): Death Blow, Desperation, Fortify Cavalry, Reposition, Glimmer and Heavy Blade Seal
- Olwen Green +1 (Neutral): Swift Sparrow, Desperation, Hone Cavalry, Draw Back, Glimmer and Atk+3 Seal
- Reinhardt Blue +1 (+Atk/-Hp): Death Blow, Lance Breaker, Hone Cavalry, Draw Back, Moonbow and Quickened Pulse Seal
- Priscilla (+Spd/-Def): Atk+3, Wing of Mercy, Hone Cavalry, Rehabillitate, Heavenly Light and Live To Serve Seal

Have Olwen kills the Brave Lance Infantry 1st, then lure them to go down one by one. I kill them outright in oneshot (prevents Lucina WoM) and stay out of Future Vision's range. At the end, I only have to deal with the Flying Killer Lance, Raurwolf Cavalry, Red Dragon and the Bolganone Infantry. With Olwen in Desperation range, it was pretty easy.

Or Reinhardt & B!Lyn Brave Bow+ with 2 dancers, or B!Roy & B!Lyn with Galeforce. No need for +10 anyway. I also clear the map within 2 turns with my Galeforce team.
