Fury Swipes is a level-up move in FR/LG only, so it creates incompatibilities similar to those of the 3rd-gen-only tutors.

Quick Attack is both a 3rd-gen egg move and a 4th-gen-only level-up move, but Doduo learns Quick Attack at level 5, so any Little Cup Doduo can learn it simply by receiving the limited training allowed (or a Heart Scale).
