If that's really from just 25 packs then you have some astounding luck!

I've opened 49 Untamed packs (almost all of them with Legendary and Alchemy potions) and have 1 Legendary, 7 Epics, and 9 Gold foils. Maybe my potions are having the opposite effect!

Also, I think you counted wrong. I see 6 Epics and 3 Legendaries in your screenshot
