In my opinion, this should probably cost

or

more than Sacred Ground, after which it is obviously patterned. Land destruction isn't particularly prevalent, nor is it necessarily very good in practice. Artifact destruction, on the other hand, is very common and is frequently very useful. Of course, this isn't especially better than Leonin Abunas, which costs

{W}. This protects against mass artifact-kill, so it would probably be solid at

{W} and strong at

{W} or

{W}{W}.
