I've always enjoyed heroes primarily for the artwork and voices it gives to Fire Emblem characters and especially my favorite characters. So these are some of the ones I would love to have a full Emblem team team of them to clear content with in the future. Some are more likely than others, especially with us receiving fewer characters overall, but here's how likely I think each is:

Very Likely

Berkut: Him being the highest scoring echoes character and reaching top 20 men this year in CYL makes him pretty likely despite the echoes debuff. (3 Alts Currently)

Idunn: Them continuing her characterization in heroes has endeared her to a wider audience, making her likely to show up again despite the Binding Blade debuff. (3 Alts, 1 bagpack Currently)

Ishtar: One of the more popular and talked about Geneaology characters and also her great design, I think, makes her likely to show up again. (3 Alts, 1 bagpack Currently)

Ivy: Easily the most likely character on my list, I would be surprised if we get to years end without her having an emblem team, then. She's the current CYL runner up and is from the most recent game. Currently. (3 Alts Currently)

Nephenee: She has one of the most impressive CYL performances over the years, I think, which makes her likely to return despite the long gap between her alts.

(3 Alts)

Yuri: Him being a lord from Three houses immediately puts him in a good position. He does great in CYL consistently and has a distinct gameplay style that gives him a great shot at showing up again. (3 Alts)

Likely

Cecilia: She's not very popular overall. However, she seems to be a favorite of IS despite this, so she might come back again despite the Binding Blade debuff. (3 Alts)

Dedue: Though he is from Three Houses, he has other factors that keep him from being very likely to show up again. He is pretty popular, so I could see him at the back of a Dimitri duo. (3 Alts)

Igrene: Same reasoning as Cecilia, including the Binding Blade debuff. (3 Alts)

Linde: Archanea usually gets some Alts for its most iconic characters, and Linde falls into that group, so I think she may come back. (3 Alts)

Lute: Despite being pretty popular, especially for a not plot relevant character, it took a while for her to receive her third alt probably due to not being a royal. (3 Alts, 1 bagpack)

Mareeta: Though she has 3 Alts, she is from Thracia and thus suffers Thracia debuff, but maybe eventually they choose to represent Thracia again they might choose her? (3 Alts)

Ogma: He is an iconic Archanea and has never dropped out the top 200 of CYL, so maybe though I struggle to see where? (3 Alts)

Nailah: Same reasoning as Cecilia minus the Binding Blade debuff. (3 Alts)

Less Likely 

Navarre, Katarina, Lukas, and Olwen were fortunate to receive an alt a years ago it's hard for me to see them completing a full team despite how much I'd like them to. If I squint, I could see one more alt for each. (Each 2 Alts)

Now, which of your favs  would you like to see complete an emblem team? How likely are they to do so?

For those who don't know what an emblem team is. It is when a character has at least for playable units in Fire Emblem heroes to fill a team.

Also, yes, I have a lot of favs.
