I've played with a few different team comps that I've thought of with a few friends of mine and both seemed to do very well when played correctly. Just curious if anyone else has any really good team comps that work well?

Team 1:
Anivia - Mid
Olaf - Top
Sejuani - Jungle
Ashe - ADC
Nunu - Support

Frost team. Hard to escape from and has very decent CC.

Team 2:
Master Yi (AP) - Top
Katarina - Mid
Kha'zix - Jungle
Tristana - ADC
Leona - Support

Team that is based off Kill/Assist Abilities. One kill sets off the entire team to a killing frenzy.
Works hilariously well if done right.

Any other teams that you've seen/played with that dominates? Let me know!

Ashe/Varus- AD Carry
Nami- Support
Kennen- Mid
Wukong- Top
Fiddlesticks- Jungle

A team based off of teamfighting. You would be hard pressed to lose late game with this team.

Zed (Top)
Lee Sin (Jungle)
Akali (Mid)
Kennen (ADC)
Shen (Support)

Let the ninja-energy-spam begin! And one monk.

Jayce - Top
Nidalee - Mid
Khazix - Jungle
Ezreal - ADC
Lux - Support

It would be so much fun.

The Ninja team with one monk doesn't work very well. Once your energy is spent the entire team is useless.
