Episode 69 of Beyblade X brought me back a certain vibe and nostalgia of Beyblade Burst.
The dynamic of that little saga of Ginro, Jaxon, Ciel, Tenka and Robin against the "dark bladers" brought me back a very similar feeling that i had on past beyblade gens.
Using beys to beat an evil group and rescue a friend, and mainly the lots of battles of Ciel against Byte, with the concept of "blader soul" and the objective of overcoming someone reminded me of lots of similar situations of beyblade burst.
On new gen, Beyblade is more seen as a sport then something that revolves every aspect in the world. But on that little saga, I felt that old feeling that beys can be used for everything.
We also have that classic situation of a character that battle repeatedly against someone evil to to overcome someone and/or oneself, overcoming on everything battle and using your blader spirit.
I liked that. Brought the the classic essence of Beyblade for the new generation, but without exaggerating.
