Magus of the History

Vanishing 3 (This creature enters the battlefield with three time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.)

Whenever a time counter is removed from Magus of the History, if it wasn't the last time counter, create a 2/2 white Knight creature token with vigilance. Otherwise, other knights you control get +2/+1 until end of turn.
