Sabrina: I don't think Lily wasn't suppose to switch out her Weavile just yet. Her strategy may be doing great, but she wasn't suppose to do that just now. Her Weavile has a Mega Stone around her neck, she could've activate her Mega Stone so that she could mega evolved. She could do the same for her Greninja, but if she doesn't pull it off and Hyman activates Tyranitar's Mega Stone, she's pretty much doom from the start. Her Weavile is the most powerful Pokemon on her team.
