Fear of Infinity
Enchantment Creature — Nightmare
Flying, lifelink
This creature can't block.
Eerie — Whenever an enchantment you control enters and whenever you fully unlock a Room, you may return this card from your graveyard to your hand.
There are some nightmares so terrible, you're never truly rid of them.

If a permanent with an eerie ability enters at the same time as one or more enchantments, its ability will trigger for each of those enchantments.
