3.haxourus
4.Thundurus(just using for fun)
5.D.Roserade
6.Typhlosion
which team member should i replace?
Also i am playing on normal mode.

Well, if you don’t want duplicate typings, try switching out the Haxorus.
Although you’ll be having fewer physical attackers, I wouldn’t worry too much.
There’s also a Mega Stone for it in Gaea Town.
