I don't think BW Series had good chemistry !
I meant Tournament ???? That All Ash can do with Friends ! How about visiting a hot spring Or have Christmas party Together Or Playing at the Beach !!!
As for communication , The game has device like Poke-gear , Xtransreciver , Holo Caster etc ! Ash can use those to maintain a communication with his friend . Unfortunately the Anime waste that idea on a Ending theme .
Furthermore , Carbernet & Gerogia acted like that they only acknowledge Ash because he's Cilan & Iris friend ! I know Ash isn't their rival But I liked to see Ash forming his own friendship Gerogia & Carbetnet . Same goes with Iris & Carbernet Or Cilan & Gerogia .
Let that aside , What do you think about that possibility of Ash getting an Aegislash ???
You remember that idea of Ash separating from the group and meeting a Power obsessed female rival who almost killed herself in order to catch an Aegislash that cause Ash coming to her rescue Only for that Aegislash to be self-caught after it got attracted to Ash's inner Leadership skill and that girl called Ash a thief for this.
So, Do You think Ash wielding Aegislash and swinging like a sword is Possible ?
Ash could figure out that Aegislash's attack is stronger when its wield by someone due to a person's Arm's velocity and use it during villainous ark .
After all , Ash wielding Aegislash like that is Unorthodox and the anime tend to show Ash like a King of Unorthodox plan.
Also ,
Isn't it be cool if Ash & that Tsundere rival fought one another over the Mega ring ??? Later Ash help her realizing her flaw .
She also could have similar past as Brock & Paul where her father left home to be a champion but never come back causing other to believe that he failed in his quest so he's too ashamed to show his face . It cause her too become the power obsessed trainer she is right now .
