Pros:
- Lots of CC, easy ganks
- Can get really tanky really easy
- Great supportive role for your carries
- Can really snowball out of control

Cons:
- Can be pretty vulnerable to agressive junglers early game
- Late game you have to rely on your team for damage
- Have to get your lanes going early, otherwise you will fall of quickly

Start with where your bot lane is, so if you are blue side you start at golems and at red side you start with gromp.
Blue side:
- Start with golems and then go to red
- after red do razorbeaks and recall for trailblazer
- proceed to do gromp, blue and wolves

Red side:
- Start with gromp and then go to blue
- After blue go wolves and recall for trailblazer
- Proceed to do razorbeaks, red and golems

In teamfights you can take 2 roles.
Frontline:
You can go frontline together with your top laner or your assasin to take out their carries. This tactic is recommended when your team is ahead and your carry can defend himself well enough.

Supportive role:
Stay with your carries and help them survive and take out their frontline. This is recommended when you have a hypercarry like jinx or vayne in your team that can eliminate entire teams on their own. This way they can deal a lot of damage and win the fights for you.
