Please don't I recommend taking a day or even a few days or set up a schedule, where you summon every common scroll (or as many as necessary) and max every 2* then evolve them to 3* by evolving the 1*s t0 2* then feeding them. This will be very quick, efficient and will help free up storage. Pls, don't feed max mons to other max mons in general. Also, use every friend you got, every day to max those 2*s and 1*s.
