Team Item Game

Okay, so here is the idea.

We all know about Team Comps and how certain Champions work together for Synergy. But I'm looking at something else here.

Going with a 'Standard Team', meaning a Support and Marksman in bot, an actual Mid, an actual Top and an actual Jungle. A general 'Meta' team.

Now here's the catch... everyone on the Team has to buy One Non-Boot Item the is the theme for the team.

What I'm looking for is:

What Item. Why.

For bonus points, name your team and how the Item will give them greater Synergy.
