This is a Myr Servitor cube I put together a number of years ago. I forget the typical method for drafting but I believe the intended format was as a micro cube of sorts and everyone would have to add 10 copies of Myr Servitor to their decks before the game started.
Rules clearly are flexible but the general intent was treat Myr Servitor for deck construction as you would a basic land. You are allowed to add any number of copies to your deck.
Primary purpose of posting this here is to document my first cube that I constructed. It's not perfect and I'm likely taking it apart shortly after posting this but it should live on somewhere.
