not really recommend umbreon for your main attacker since umbreon have low atk. Some players use umbreon for stall instead.
if you really want flinch so badly, i might recommend togekiss with Serene Grace and air slash.
your wanted pokemons overall weak against fighting except talonflame, some fighting have rock moves too which is annoying for talonflame.
If you want a long run party, you need to think about it again, 6 "glass cannon" type is no good especially when you fight bosses in the game.
yes "by breeding" means all, if you see one of move missing, please report us.
