Alright, i need some help beating my friend.

His Team :
Crobat
Blaziken w/ Megastone
Ampharos w/ Megastone
Jynx or Lapras
Greninja
Drapion

He always used Crobat, who is fast, and Jynx to get me with a mean look and always uses that fucking Mega Blaziken. If anyone knows a good team to beat him with, that'd be a big help. I used to beat him always until he finally used the megastone for Blaziken. OP as fuck. It has a speed boost as well, which makes it impossible to hit.

TL;DR looking for a team to beat his pokemon and Mega Blaziken

Thanks for reading! Please leave some help/tips
