@Quick Rawr the weakest karthus would burst all the banshee veils while the other 4 stacking deathcaps clean up easy =D

I'd have a team of 5 Katarinas, they'd be like ninjas suhunpo-ing and spinning everything to oblivion =D

how about 5 kog'maws? think about somone in a turret get missle barraged by 5 kog's

5 pantheons vs 5 pantheons, epic game of Spartan leap frog.

5 Ezreals.
YOU YOU YOU YOU YOU BELONG BELONG BELONG BELONG BELONG IN IN IN IN IN A A A A A MUSEUM MUSEUM MUSEUM MUSEUM MUSEUM.

'Nuff said.

Another good team would be five sorakas. 70 mr aura, multi starcall with rylais and spell vamp, free mana on lane and a sequence of heals and wishes. *feels like a battering ram*

5 Karmas.
Just because I've never seen 1. 5 at one time would be overkill.

5 Brands, can somebody say PyroCLASM!!!

5 Kog Maw

WWII bombardment would seem NICE when faced with 5 living artilleries
Lets not forget 5 wide, non-stoppable, skillshot slow. (oh yeah baby, ur not getting anywhere near close)

Changed my mind

Embrace despair with 5 kennens stunning you until you break you keyboard from frustation.

5 fiddles would b fun too fear and ultimate for everyone!
