Incoming Solo Team

I just realized that L!Marth's Fire Emblem had an effect no matter the distance.

Except healers I believe he is the only unit who can buff from afar, and 4 to each stat is not ridiculous. And with the lauch of the first great Solo skill, I was thinking of "solo" team.

So my main would be
L! Marth (+Hp/-Spd)
Exalted Falchion
Smite
Fire Emblem
Solo Atk/Spd 3
Wrath 3
Spd smoke 3 (Or a wave skill to fit with his falchion)
Spd 3

Then L!Ephraim is a really good candidate for solo team with his weapon effect

L!Ephraim (Neutral)
Flame Siegmund
Reposition
Galeforce
Solo Atk/Def 3
Chill Atk 3
Def Smoke
Heavy Blade

But I also hesitate with L!Hector who has Ostian Pulse but thunder armads has an eantagonist effect to solo teams.

That's the start of an original team building, but then I have not many more ideas to finish it. I need at least each color (colorless is not a color btw), and a unit who can do magic damages, I was looking for a unit who can use infantry pulse (if not ostian pulse) and who can effectively benefit from the (+6HP, +4 def and +4 res) from L!M and L!E seasonal bonus. I also thought a ploy user can be useful cause they can be effective with allies being far.

Of course we need the new solo skills to be fully released but as they will be very power full and I haven't really seen a team with all unit working independently, any ideas guys ?
