This is my first team build so dont get mad if you dont like my team. I like to play this team because u have tons of damage output, and plenty of stuns. I usually have ryze solo and have him get stacked. Amumu is your team tank, so get lots of health and AP with him. Olaf is your DPS/Tank, so build strong, but yet tons of atk damage. And ryze.... well you know how to build a good ryze.

IF u have a smart team, you will always win in team fights.
When i use this team... we always win.... there is no cons.

It doesnt matter about ur masteries and runes... just get what you think you need, also for skill sequence, just level up your favorites and just use what you like.
