Eater of the Dead by tapping it, causing a player to mill cards equal to its toughness.
Activate
Eater of the Dead by paying ({0} magic symbol) , exiling a creature card from a graveyard and untapping
Eater of the Dead.
Repeat as able.
Notes
The combo stops when there are no more creature cards to exile. You may boost
Eater of the Dead's toughness to minimize the chance of this happening and/or tap additional creatures if you run out of cards to exile. You can also repeat this on subsequent turns.
