Michialis, Cerche, or Minerva?

Cherche with a brave axe is the strongest for sure

+atk/-res cherche with brave axe+ and deathblow 3

Cherche is easily the strongest attacker, but Minerva and Michalis have way better enemy phase power...

Cherche for pure raw power during player turn.

Minerva has a less powerful player turn, but she's strong, even during enemy turn.

Michalis is not that good tbh.

It depends on what you're looking for...

Cherche has one of the highest ATK scores in the game and gets many ORKOs with a brave axe... Her HP and DEF are great as well but her RES is rockbottom.

Michialis is equally straightforward. He's an excellent tank with respectable ATK and DEF, but sad SPD and RES. On the budget side, he's one of only two fliers with a legendary weapon (its basically a super killer axe) and doesn't need to inherit anything.

Minerva is the most flexible of the three. She can be a sweeper with LnD and flier buffs...but she can also be a more balanced tank as her RES isn't rock bottom and her SPD approaches decent. She's also one of only two fliers with a legendary weapon -not only is the weapon itself great, legendary weapons are great for arena scoring.

Personally, I would go with Minerva if I had pulled one with decent IVs but instead I'm going with her brother. Cherche is powerful...I raised one to 40 early on...but my flier team could use the arena scoring boost / a unit that's better at baiting.

Well i have a +SPD/-res Minerva and i can Say she is One of my strongest unit. With lnd and desperation She reach 41 sped her def still good enough to Tank then kill someone. With her weapon you can run any special. Under desperation range She kills anyonee. Minerva Can be used as good Tank too without lnd due her def and speed. Her Brother has Better def and Attack but really lacks Speed so he is a defence unit especially with qr(still he can't have ivs).
Cherche actually has Better Attack especially It you use a brave lance and db, She still has good def and and ho still her low Speed especially with brave Axe per her being double by Anyone less with flier buffs. So or course It depens on your use but generally Minerva is Better, still cherche is more offensive unit while michalis Isa Better Tank but usually Minerva Can do almost both of them. To each 3 of them do not let the. Being hit by any kind of magic, ( Minerva Can maybe Tank 1 single Blue tome blow without Blade tome due her Speed but do not do that)

I've never summoned Minerva, but she seems much more dependable than the other two.

Cherche is frighteningly powerful on attack phase, especially with brave axe and goad/hone fliers, but her low speed and nonexistent res means she drops like a fly when hit. Fortify Fliers might alleviate that, though.

Michalis has.... defense? IDK, I've tried him several times, but always banish him back to the bench two battles later, lol.

I have both a Minerva and a Cherche and I can say that Brave Cherche is a legend that lives up to your name, but is similar to Berkut in the way that she has no defensive power. 32 defence is actually worthless when she gets doubled by the entire cast with only 20 speed.

Minerva on the other hand is more flexible in terms of build diversity and has the bulk and speed to tank hits when not equipped with LnD and become a powerhouse with it and her Hauteclare equipped.

I can't speak for Michalis, but I think the only thing going for him is his unique skill and defensive bulk (Attack is good too).

All in all, Cherche's build is crazy expensive but flier mobility, ability to support team with reposition, and her one shot potential works really well together for her kit and play-style. So my vote goes to Cherche.

Minerva can also give LnD and Ward Fliers, Michalis gives Iotes Shield, while Cherche gives nothing but Attack+3 snd Pivot.

Edit: If you run Cherche on Flier Emblem though, your entire team will basicslly run very similar sets and play-styles so do keep that in mind.

You said your Minerva is +Speed? She's killer even on her own and is the greatest flier in general in my opinion, but Cherche is wreck sauce on anything she initiates on as long as she has a brave axe+.

I have a +Attk 3* Cherche, given her a Brave Axe+ already. I just gotta get DB and raise her up.
