I might have figured out Fynx' and Lumi's rarity

TL;DR They are both mythic if there isn't any dev build magic involved

Hopefully there's no Dev build magic behind what i'm sharing with you. While watching Ferre's (italian youtuber) sneak peek video, i noticed that while in the brawler selection screen, it showed that on his account there werre corruently 90 brawlers. Meaning that both Fynx and Lumi are both unlocked on his account. Now, later in the video he has shown the transition between epic brawlers and mythic brawlers in the selection screen, as seen in first image the image. And since neither of them are present, we can assume that beither of them is an epic brawler. Later, while looking through the legendary brawlers, he scrolls down to the bootom of the screen, and still, no new brawlers. But, as you can see in the second image, kenjy is in the last spot of the last row, which does not resemble the way it currently is in the game (last image). Meaning that before kenji, 2 bralwers have been added, and since the video doesn't show the transition between mythic and legendary brawlers, we can safely assume that Both Fynx and Lumi are mythic brawlers.
