You might want a Galvantula as your opener.
Just get off Sticky Web and you're in pretty good shape to sweep.
Galvantula with Sticky Web, Volt Switch, Thunder, Bug Buzz.
Ability: CompoundEyes
Item: Focus Sash
EVs:252 speed, 252 spATK, 4 HP
Nature: The one that decreases attack and increases speed. (Most likely Jolly or Timid)
CompoundEyes helps your STAB Thunder's accuracy so it can hit pretty hard and misses not too often. Your Focus Sash is to help you survive a hit and lay down the Sticky Web for sweeping purposes. Volt Switch is pretty nice for switching and Bug Buzz is a STAB move that can hit through Substitute. This guy is mainly used for Sticky Web to make sweeping a whole lot easier.
You now have 2 rock weaknesses and 1 quad rock weakness.
You also have 1 fire weakness and 1 quad fire weakness.
The disadvantage of having Galvantula is your team's rock weaknesses.
(It's my first time posting in competitive so I hope I done something right)
You're referring to Timid here.
Anyway, sets for each Pokemon.
Infernape is one of the best mixed attackers:

-Close Combat
-Thunder Punch
-Mach Punch/Hidden Power (Ice)/Grass Knot
Nature: Hasty/Naive
EVs: 168 Atk/88 SAtk/252 Spe

Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe

Nature: Adamant
EVs: 252 Atk/252 SDef/4 Spe

Mega Scizor is so bulky; take advantage of that:
