Anyways, I was watching the vid on youtube and some champ selections came to mind.
The first team that came to mind was;
Basically I'd imagine a decent AP tank, ranged attacker, 2nd AP off-tank(gragas and amumu do massive damage early game anyway, plus both ultis disable the enemy), Attack speed/crit based champ like tryn or yi for mashing noobs, etc, and of course an AP nuke(Annie and brand chosen for stuns, their ultis and whatever else they have).
Not sure how it would work, but if death results in you having to sit out for a period of time, then being able to smash the enemy asap would be the most beneficial route to victory.
Both teams are reasonably well matched, both have plenty of CC(knocked airborne, stuns, slows, attack speed reduction) from lvl 1, all are reasonable 1v1 fighters(with the exception of Annie/Brand, and occasionally Singed). If there is fog of war still, Nidalees bush(brush?) traps could be useful in stopping the enemy asap(same for Teemo)
Other viable options imho would be Jax, Pantheon and Shaco(maybe, he is fast and could be good to collect quests if they only require 1 person).
