It's also a great candidate in decks that can add more counters to remove your opponents' window to play around it: I'm getting tired of mentioning Atraxa, Praetors' Voice, but unsurprisingly she's incredibly good with Scriptures, letting you cast Scripture turning her into an artifact and immediately wiping the board while keeping her around

It then establishes an unassailable position via countermagic and wins a slow victory via Snapcaster Mage
