Okay, side stepping a bit.
Title: Mysterious Mega Evolutions in ASB
Gist: Mega Evolutions happen at A0 of any round a pokemon is ordered to Mega Evolve. However, can a pokemon Mega Evolve on A2? If such an order is posted, is the Mega Evolution performed at A0 or the Mega Evolution is cancelled for that Round?
Story: Gerard in his
Psychic Gym battle vs Frosty, wanted to make life difficult for me, by venturing into this part of Mega Evolution. So as Frosty has posted in the battle, the handbook says that a pokemon can Mega Evolve at action 0. And Gerard is claiming that, this would imply that a pokemon can choose to Mega Evolve before any action in a round. I agree with Frosty on this, that the handbook mentions a possible outcome and it doesn't have to deny all impossible outcomes (Although if there is a statement saying, 'No other option is available' or something similar on those lines, it would avoid a lot of grey areas).
But personally, I don't understand why Mega Evolution is restricted to A0. If we go with Ingame precedence, then this would be the perfect mechanics in ASB. But will things be broken, if we allow Mega Evolution before any action in a round? It does create some problems when types change after Mega Evolution, Although I am still getting used to balance in ASB.
Summary:
1) Can Mega Evolution happen on any action other than A0?
2) If a Mega Evolution is ordered on A2, is it ignored? Or the Mega Evolution is performed at A0 for the trainer?
