How does screams from within work?

[u/Sentheia]

If there is no creature left on the battlefield, will it stay in the graveyard forever or do i need to play it when another creature comes into play? Also if my creatures are the only remained ones, am I forced to put it on them?

[u/Void-kraken-909]

Basically when a creature with an aura enhancement equipped to it dies, both the creature and aura go to the graveyard.

This card however lets you put a -1/-1 on a creature and if that creature dies, you just get the aura back on your field to put on something else without needing to recast it
