My bet is that V15 and V16 are mostly post game stuff (just a small guess). Yet I cannot wait for V13.5 to come out and thank you for making me like Rejuvenation again
Now it's time for some team predictions, because whyaut:
The last 3 Gym Leaders (as for the E4 teams I'm not so sure):
For Alice (Dark Gym Leader): We know that she will have a Sableye (safe a Mega) given the events during the Unknown Dimension. Prankster ability + Quash to postpone fast moves.
For the rest, I say: Liepard, Honchkrow, Zoroark, Grimmsnarl and Bisharp.
For Allen (Fairy Gym Leader): We known from the Unknown Dimension events, that he uses an A- Ninetales (which would be his signature Pokemon). Safe for Snow Warning + Aurora Veil 100%.
For the rest:
Prankster Whimscott (for Tailwind setup), Azumarill, Florges, Alcremie (Mega/Dynamax form), Clefable (bulky with Magic Guard)
As for Damien: Well his team got revealed in Ch15, when he fought a part Storm-19 along with Alexandra, despite having a mix of Dragons and Darklings as well (so the siblings might be an expectation). Same goes to Alexandra with a mix of Dragon and Psychic types.
Yeah that's my predictions. But I'm not sure for the next update. I'll let myself get suprised
P.S: I wonder if we will time travel yet again for the 4th time for more answers about Nymeria's fate. Amd I hope we'll see Nim again for more action.
