I'm not against using it to self mill to get a win with Jace, which sounds like it'd be a VERY good win con combined with Archmage Emeritus, Thousand-Year Storm and Veyran, Voice of Duality, or to fill the graveyard for me to cheat something out with Narset, but I wouldn't really consider that ideal in that circumstance because the ideal situation (in my mind, at least) is I'm using Narset to cast something twice
It helps you load the graveyard too
