Egwene, Flame of Tar Valon

Whenever Egwene, Flame of Tar Valon attacks,
choose target creature you control, then roll a d20.
-1-14 | Create a tapped and attacking token that's a
copy of that creature, except it's not legendary and it
has "At end of combat, exile this creature."
-15-20 | Create one of those tokens. You may roll
again.

"Let the Shadow know this: as long as one of us
remains, the Light will never be extinguished."
