My OP theory on how to never lose.
I believe a ranked team would go undefeated if their champ selection came from this pool each game.
Tank =
Support =
Marksman =
Mage =

Jungler =

My ideal team is
20% damage reducation in team fights.
healing.
high AoE armor reduction with sniping from 1000 away!
Missile Barrage.
Noxian Guillotine. Take us home Darius.
Agree or disagree? Why?
