Ah I actually wasn't familiar with this mechanic. So it would essentially allow the earlier version to learn the moves prior to them actually learning it?Figured it was worth bringing this up: Breeding on level-up moves so the Pokemon learn them as they're born as lost quite a bit of relevance, now that you can just use the Move Reminder to get later level-up moves early, so you don't have to breed Hydro Pump onto a Psyduck if you want to use a Hydro Pump Psyduck in for example LC.
The only times this is relevant is for Level-up moves from previous stages, like Spore on Breloom. So like in case you get rid of Spore after Evolving, you can use the move reminder to get it again, whereas if it was bred without Spore as an Egg move, it would've been lost forever.
Ie: Psyduck learning Hydro Pump at lv5 is possible since it eventually learns it through level up?
Is it safe to assume that these younger versions will not be able to learn moves exclusive to their later evolutions?
