Aetherplasm
Creature — Illusion
Whenever this creature blocks a creature, you may return this creature to its owner's hand. If you do, you may put a creature card from your hand onto the battlefield blocking that creature.
Its fickle form holds hints of a thousand former identities.

Although the creature that enters the battlefield is blocking, it was never declared as a blocking creature for the purposes of abilities that trigger whenever a creature blocks (such as Aetherplasm's ability, for example).

The creature you put onto the battlefield may be the Aetherplasm you just returned to your hand. This allows it to dodge abilities like Deathgazer's.

The creature you put onto the battlefield from your hand is blocking the attacking creature, even if the block couldn't legally be declared (for example, if that creature enters tapped, or it can't block, or the attacking creature has protection from it).
