I've seen alot of branch evolution polls, so I decided to make a q & a for breeding.I'll show you:
Let's use the ever famous eevee family. NOTE: Leafeon and glaceon must be traded, there is no way besides hacking to get them, trust me, I've tried. OK, first, put eevee and ditto in the daycare. Walk 256 steps then check with the man or call him. Keep doing this untill you get the call, you got an egg! use a pokemon with Flame body next to the egg to speed the time up. When it hatches, pick the eeveeloution you want. Keep doing this untill you have all of the eevee family you want. Yes, this works for every pokemon breedable.

Most of the polls refer to players who want to use a certain evolution for the purpose of completely the main story or a certain part of the main story. Or maybe they're looking for a branch evolution to be a part of a competitive battling team (although most branched evo Pokemon aren't necessarily going to dominate most battles). As a trainer who enjoys collecting all Pokemon and doesn't choose one or the other when you can have them all, I understand where you're coming from, but other people have different ways of thinking and playing Pokemon.
