Mono White Control

lock down the board while denying your opponent mana. play all the best white cards. im a big fan of white decks and i am always trying to make a white deck thats solid against every matchup. i think with this i have found the answer. we have land hate for decks like bloom titan and tron, while not sacrificing having a strong midrange matchup with the powerful late game in emeria, the sky ruin and sun titan. using sun titan or crucible of worlds we can start bringing back ghost quarters we lost earlier or bring back plains to get emeria going. also if emeria got tectonic edged this gives us inevitability without having to play 4 emerias to get it. leonin arbiter and aven mindcensor solidify the land destruction package while making path to exile better. while leonin arbiter can be a nonbo with knights of the white orchid, flagstones, and weathered wayfarer we can always pay 2 should it come to that and we get to set it up so its favorable to us. flagstones of trokair are too powerful with crucible of worlds to pass up imo and help a lot with recovering after a death cloud or liliana ultimate. they also provide deck thinning which is nice when we dont have any card draw and just eek out card advantage through board wipes, recursion, and planeswalkers. the other benefit is that since we are white we have access to all the best (imo) hosers modern has to offer. im looking for feedback on card choices and sideboard strategies to shore up what you think may be bad matchups. thanks!
