Nightmare Recovery

Search your deck or graveyard and put
to the battlefield card with name
Erash Ir-Ezmir, Harbinger
and card with name Ethar, Herald of Nightmare.
If you must put Omen or Nightmare tokens,
double the number of tokens gained in this way.
"While Illur and the surroundings slumbered
in ignorance, the nightmare from the past had
almost returned".
