Who would be the best commander for a mill deck? I've tryed various styles and just can't get the flow right. I know personal opinions mix on mill but why not list what you would most hate to see sitting across the table.
{Lazav, Dimir Mastermind}
{Wrexial, the Risen Deep}
{Szadek, Lord of Secrets}
{Circu, Dimir Lobotomist}
I made a very fun (and effective) EDH mill deck commanded by {Damia, Sage of Stone}. Her colors are perfect, and she keeps the cards coming so you don't lose speed mid to late game. I'd definitely reccomend giving her a shot if you haven't already.
{Mirko Vosk, Mind Drinker} maybe? Most common is {Oona, Queen of the Fae} I think.
Mirko Vosk, Mind Drinker!!

All the Dimir potentials <3 love me some Dimir/Mill.
I like {Circu, Dimir Lobotamist} a lot.
