I'm also trying to make a competitive standart mono white deck. I'm a little curious on why you decided to use Beloved Princess instead of Hushbringer, with the current standart I see Hushbringer being more useful (and it also as lifelink). With the new Heliod every creature kinda turns into an Ajani Pridemate so wouldn't it be better to try and put other lifelinkers? Reverent Hoplite + Impassioned Orator seems a good synergy although I'm not liking it for the mana cost. I hope we can help each other to brew a really good deck :)

Beloved Princess also has lifelink, is one cmc, and has a pseudo evasive ability. Additionally, being one cmc, the opponent generally will have to use more mana to get rid of it than I did to play it.

Other than that, this was a first draft. I don't know if the Princess will survive the cuts to the final version.

That being said, I love Hushbringer . It will probably end up in the SB if it doesn't get a MB slot.

You should check out the deck me and Soggybottom85 were brewing maybe you can get some ideias from there we're all trying to build a mono white deck and see the discussion as well.

Have you considered Daxos, Orator? It feels almost like Daxos would be a great addition instead of Linden (or keep both) since he has so much toughness ussualy and grants you a payoff when you get your board wiped

I have considered, (actually there's a piece in "Recent Changes") but I don't think having a 2/* helps a weenie deck, and I wouldn't call gaining life a payoff to a sweeper.

Linden, the Steadfast Queen on the other hand has good starting stats and Vigilance in addition to the fact her ability pumps your team with Heliod, Sun-Crowned out.

Thank you for to your comment!

I don't know how you feel about these suggestions, but what about Giant Killer (removal and a body) and Venerated Loxodon (a card you can get out on the field by utilizing your board presence. Let me know what you think, I don't think it should throw off the curve that much.

Maybe remove a Heliod and a Hushbringer?

The Loxodon potentially can be an 8/8, by the way.
