I was just thinking, if the merchandise is actually true, it could be indicating some pretty rapid boosts for the classmates, such as Vikavolt for Sophocles, Brionne for Lana, and possibly Lillie getting Ninetales and mastering Subzero Slammer, all for the reason of possibly making them eligible for a potential league. I'm getting more and more convinced that this league is going to be more of a friendly style school tournament, and I won't be surprised to see 1 vs 1 and 2 vs 2. Illima, Hau and Gladion competing wouldn't be that weird anyway since they are well known to Kukui and I'm sure he'd invite them anyway. A potential Ash vs Gladion would likely be the main battle for this 'league', either a 3 vs 3 or 4 vs 4 (depending if Noivern is actually Gladion's Pokémon). I seriously want to be wrong about my prediction cause I would hate such a scenario, but the way the series is going, it's only adding to my prediction instead of easing it.
