>>33340666Infinite Energy infused Z Crystals. The purple swirl in the initial trailer got me suspicious, and the Z Power Kommo o Crystal confirmed it for me. Z Power Crystals offer a stat boost because of the infinite energy, but dont trigger a mega evolution because said Pokemon likely doesnt have one. Which makes me wonder if they might retcon mega stones into Z Power Crystals, and thus have a work around to introducing new megas.
Z-Moves=Basic Crystals and Pokemon Exclusive Crystals
Z-Power Crystals=Stat Boost and Attack OR straight up mega evolution.
There might even be something else as they mention other uses for Z Moves in the Power Ring, which might mean instead of new Z Crystals for mega evolution, regular Z Stones mega Evolve Pokemon with a mega evolution based on type, but that might require major retcons in the future.
