Two or three times each day I feed my current hero roster the accumulated feeders. Finding these targets among the dozens of stored heroes is tedious. So, I’ve simply set the five heroes I’m training (yes, I strongly believe in matched-color training) as Team 1. That puts them across the top of the screen, making it much easier to find them (and not their evil twin sitting at 1-1).
I do the same thing, but with team 2. Team 1 is my defense team, team 2 is the ones im currently leveling, team 3 is new heroes that I’m trying out for farming, team 4 is empty, and team 5 is set for the current titan
