Totally agree on the potential of Shield Mare. But as you mentioned, it’s one of those cards that appear to be just impactful in one matchup.

I was also thinking of trying it in a company deck but it already has Kitchen Finks. Although, it does have an edge over the ouphe when expecting graveyard hate from the opponent.

On other potential sb cards, there are a few more but they lie mostly in the “might be good, but is actually quite narrow” category.

Cheers!
