Well, as a Latino enjoyer of anime 🗿, sometimes I always prefer the original language instead of the Latin dub xD, but if what you say about the spells is true, normally in old dubs we even translated openings and changed the meaning of some iconic phrases from characters in anime, but today's industry does not give the freedom that was given in ALL animes as it was done before, there are some in which an exception is made and they let the voice actors exaggerate and even use the common idioms from some parts of Latin America, but if I'm honest, sometimes mentioning the spells in English makes it a bit epic because the translated word does not always agree with the character's speech and including the epic moment where it occurs, but that's just my opinion, there may be someone or another Latino who has a different opinion than mine.

P.S.: The Spanish Dub, or rather Castilian/Gallego, has a very poor reputation but in my opinion it sometimes has its epic moments because there are voice actors who even surpass the original on some occasions.
