I always thought it was the beginning of your own turn. Huh
Has it always had that? I still never had issues with it. Meh.
Sleeping lasts a max of 5 turns, grass moves are halved in power against flying (Charizard’s second type), and it’s a weak move to begin with.
I also don’t like the idea of mega evolutions anyways. They look cool, but it’s a weird gimmick. Never got the real purpose outside of bigger numbers.
