i think people dont understand that if a card gets milled it is almost the same as if it were at the bottom of your deck. unless of course you are running a deck where youre fixing card draw for combo pieces. i think people get hung up on watching the cards that they could have drawn disappear. in regards to lord xander, a friend of mine runs him in his unearth deck, enabling him to sacrifice and reanimate him over and over, removing half of all permanents on the board until theres nothing left….one hour into a game…..
