Hey! So me and my brother have an interesting question. It may have already been answered somewhere, but I'll go ahead and ask again since I can't find it. How does Force Cage affect Spiritual weapon and/or Blade of Disaster from Tasha's? Can you cast you spiritual weapon/blade of disaster in the cage and then move it out? If it is already up and force cage is cast so that the spiritual weapon/blade of disaster is inside the cage, does it drop? Can you then move it back outside of the cage?

If you're using the barred prison, you can cast any spells into or out of it.  If it's the cube version, you can't cast any spells into or out of it.  With Spiritual Weapon or Blade of Disaster, I'd be inclined to say that they can pass through the cage version due to both being a spell effect, not a creature.

Cool but if it's the solid version you would say no go? 

The solid version explicitly blocks all spells and effects, so it definitely can't go.
