If you could get any 3 units free, who would you pick and why?

Alm, another Alm, and a third Alm

If no duplicates allowed, Alm, Gray, Summer Innes

Hector, hector and hector, DC fodder for life

Red is true hell, so I would go with Alm, Zelgius and YT Olivia as I'm missing all three and they will probably not show up in legendary banners again.

For merging projects I would pick LTiki, LHector and Surtr.

Dorcas, I really one. Make that +Res/-Spd as well (even tho free units are neutral, but I don’t care :D) Always wanted to invest Into Dorcas if I ever summoned for him, could +10 him if I had the money.

Laevatein, I just want to see how Op that blade is with loads of buffs.

Ophelia, that tome looks really Op. I have all the fodder just for her.

Honourable mention: Hector, who wouldn’t want free DC?

Legendary Hector

Legendary Marth

Nina

Honorable Mention: a second Nina, I need that Link for my Canas.

H!Nowi,H!Niles,L!Marth.
1.Nowi=Favorite Character Pulled One,Need Merges.
2.Niles=I Like Him And He Can Be A Great Unit
3.Marth=Because It's Marth And I Like His Design.

Sutr, Legendary Hector, and Zelgius. Because top tier.

L!Marth
L!Hector
L!Ephraim

I just can't summon fire legendaries.

Stupid answer but Elise. I've been playing since release and have NEVER gotten her. There's less than 20 units (not including alts) that I haven'y gotten and I just want my sweet sweet perfect darling beautiful daughter so I can love and cherish her for the rest of my days.

Bride Charlotte - one of my most wanted seasonals
Mist - only Tellius unit I don't have, unless she gets demoted, then Ophelia
Valentine Lilina - mostly to avoid dealing with color sharing on next year's re-run

Spring Chrom, Winter Robin and... eh... I have no idea XD Legendary Ryoma or Summer/Festival Xander

Lucina, Spring Chrom and L!Robin since I like Awakening.

L.Tiki, L.Marth, second L.Marth if doubles allowed otherwise I'll take L.Lucina. Legendaries are expensive to pull and not even available via pitybreak.

Close competition: Lewyn, M.Azurcorrin, Kliff, Ophelia, B.Veronica, H.Mia, B.Ephraim, B.Hector, flying dancers

Adrift Male Corrin, Kliff, and Summer Leo. If I can't manage to summon Hrid, he would beat out Adrift Corrin.
