Emmara, Soul of the Accord offers a more inexorable approach to token creation, allowing you to take advantage of ways to untap her on opposing turns or repeatedly tap and untap her with specific card effects like Paradise Mantle, Reconnaissance, and Staff of Domination
The Azorius (White/Blue) colors offer a more controlling, value-oriented game plan
This can make this card pretty useful with some decent protection
Blood Artist An engine card that pretty much defines an archetype all by itself
This also means that if either ability is countered (with Disallow, for example), the other ability will still resolve
I think most people expected something really splashy when it came to Urabrask, and on first read, this effect is pretty underwhelming compared to the game-warping effects of the other new Praetors
