Mia's Unho-ho-holy Judgement.

So after 100 Orbs of almost nothing on my 1st try on the Winter Banner the 1st day it came out, I gathered 75 Orbs since that day and decide to do another try on the banner today. Didn't really do well in this either because my pity rate was broken by these two Red Units.

1st of all, is it too much to ask for Winter Tharja and Robin, literally the only ones I'm going for at this point.

2nd of all, the main highlights from this summon were basically:
1. My last 4* Odin which I finally made my +10 Merge and planning on promoting and building him after the trials end.
2. One of the Pity breakers, Leo, my personal favorite Nohrian Royal. (I'm bittersweet TBH, has good IVs but came at the worst possible time.)

And then the other Pity Crasher was of course Mia. And her IVs are the same as my Ayra, +Def/-Atk. I'm wondering if I should keep her or just give Flashing Blade to some other unit out spite. If you guys mostly choose the latter who should I give this to?

Athena
Lyn
Tharja (IDK if that would work..)
Not Ayra obviously since she already has that.
These are the fastest units I have.
