Favorite thematic team comp?

A couple times years ago, some friends and I tried something fun. We set out to all play champions that are allied to a faction. I mean, who wouldn't want to try it, right?

We tried the Demacian Commando's comp, with Galio, Xin Zhao, Lux, Garen, and Jarvan.

Yea we didnt have an adc lol, we sent Garen and Jarvan bot lane xd. Tho this was years ago when this didnt matter nearly as much today. We just play safe for laning phase until we hit lvl 6 bot lane.

Then we dunked their butts.

This comp actual has huge synergy with eachother. Having a Garen, Jarvan, and Xin jumping at you is terrifying. Having (old) Galio with his aoe taunt ultimate, and Lux with more AoE magic damage, and it becomes very difficult to actually teamfight against these Demacians. The success of the game was fun and hilarious.

A year or so later, I tried another team with different friends. We went for the full voidborn comp.

That means no Malz or Kass, but void born.

Cho'gath top. Rek'sai jungle. Kha'zix mid. Kog'maw adc. Vel'koz support (lol you mean my kills bot lane).

Just looking at those names with eachother felt satisfying enough. But the game was actually so fun. Can you imagine trying to teamfight a comp that has a Cho knockup and silence, Rek knock up, Vel knock up, along with all of their AoE damage, a Kha bursting you, and Kog firing artillery at you?

The impression i got is that the Voidborn teamcomp sows chaos, and what few teamfights we fought, we won decisively. I actually have a hard time thinking about how to fight the Voidborn if they know what they are doing.

Doing these themed faction team comps was some of the best games ive ever played, and i really want to try them again sometime. Maybe we could set something up someday ;P

So, what do you think your favorite thematic teamcomp would be? Noxian? Yordles? Zaun or Piltover or Shuriman?

Let me know what you think :)
