Why have a complicated explanation for the lore behind these transformations if they’re just going to scrap them later anyway? Why can’t it just be...

Mega Evo: “Oh now we found a way to temporarily put Pokemon to their max potential using these stones!”
Dyna/Gigantamax: “We found out that we can use this method to make Pokemon huge and powerful temporarily in battle and we’ll let competitors use this to their advantage in certain areas!”

Why the alternate timeline or the projection hologram but not actually a projection hologram shit? Why not keep the explanation simple?
