I get very into everything I do Ill preface this with the fact that I go as far as to sort my basic lands per set, my tokens alphabetically and I even know exactly where my keyword-counter, art cards and how to play magic info cards are
It can hold a similar function to Vishgraz in your three card combo
Its controller creates a Mana Confluence token
