Shallan Davar, The Lightweaver

{2}{w/u}: Create either Radiant, Knight of Honor, a legendary 4/4 white Illusion Knight creature token with "Illusions you control have myriad." or Veil, Keeper of Memories, a legendary 2/2 blue Illusion Rogue creature token with skulk and "Whenever an Illusion deals combat damage to an opponent, scry 1". You cannot have both tokens on the battlefield simultaneously.

Whenever an Illusion you control leaves the battlefield, you may return Shallan Davar from the graveyard to the battlefield.
