Your vigilant knights will slowly gain greater control of the board for as long as she remains out. 

W/B Knights on Wikia

 W/B Midrange is a combination of the Vampires and Knights archetypes. Both decks share a common core of supports cards, although a lot of pilots favor Knights as the meta shifts. Vampires got very little from Dominaria. Knights got enough to be viable, although there are some who would argue it was viable before. Both strategies overwhelm you with a wide net of threatening foes. Each deck has a token plan underlying it.

Both decks run an overlapping suite of removal and support spells. Both decks benefit from Radiant Destiny, turning any field into an army. Cast Down, Cast Out, Seal Away, and Vraska’s Contempt are all excellent options for removal. Vampires has more cheap threats like Legion’s Landing and Champion of Dusk. Knights is slower, relying on Aryle, Knight of Windgrace and Benalish Marshall.
