Hello, first of all congratulations for the work you dedicate to the game.
My opinion is that prestigious mounts can only be obtained with PVP coins. But you can achieve the particle effects with PVE coins, not only that, but also the ability to mega evolve mounts with PVE coins, such as Rayquaza, Latios, latias, kyogre and others.
I hope you read me, thank you very much.
