Stupid question about Graveyard:
Technically the only times buried units are removed from the special Graveyard/buried zone are: "Sacrifice Graveyard when four or more units are buried in it (and discard those units).“
And
"
→ Play a buried unit. (You still pay for it and must meet the tech reqs for it.)”
In similar nature to the Prynn Trashing question – if someone breaks, destroys, trashes or otherwise removes graveyard from play outside of it becoming too full and being sacrificed by its own ability, are any units buried there gone?
The additional rule in () seems like it is maybe a reminder style bit of text.
