I have an Extus/Awaken the Blood Avatar commander deck and I have Arcane bombardment to capitalize on a Sorcery as a commander. Let's say I cast Awaken the Blood Avatar and instead of returning it to the command zone I leave it in my graveyard to later be exiled with Arcane Bombardment.

Now, as a result of Arcane Bombardment moving my commander to a new zone, I choose to move my commander back to my command zone as a replacement effect. If I elect to cast Awaken the Blood Avatar from my command zone, will Arcane bombardment be able to cast a copy of Awaken the blood Avatar despite it no longer being in exile?

Is this similar to a situation if someone were to exile a commander with The Mimeoplasm and the commander is returned to the command zone instead? There are also Ingest creatures that might attempt to try something similar.

TLDR: Does Arcane Bombardment still make copies of cards no longer in exile that were exiled with Arcane Bombardment?
