I'm one of those lazy people
Though I also occasionally use an alternative RB poker when necessary: I reserved unit #5 as prep-unit for Nation Battles, and it currently contains the Winter Rose team. There aren't many Winter Rose girls, and I obviously didn't max out all the 2* and 3* girls from there (yet).
