It's an artifact, and plenty of cards care about artifacts entering, leaving, or being on the battlefield
In the final chapter, The Argent Etchings blows up everything in play except artifacts, lands, and other Phyrexians.
Blue Suns Zenith Blue Sun's Zenith is another blue card thats just too fun not to play but also fits this theme
Otherworldly Gaze If you count Surveil spells as self-mill (and I do, given how rarely you see triggers that care exactly how cards end up getting from your library to the graveyard), then Otherworldly Gaze is as good a choice as any for the most consistent, efficient, no-bells-and-whistles version of the effect
This deck really lacks card draw, but Signed Contract works well to turn that around
