While graveyard hate and an anthem effect is an already solid use of three mana, General Kudro's activated ability provides it with an additional layer of value

One other subtle strength here is the degree of control you can have over exactly when cards are milled, and how many (assuming you have painlands or other unrestricted self-damage sources)

Druid of the Anima and Drumhunter are a couple of my favorites

In another word, cEDH generally means that your deck has a power level of 9 to 10.
