Well met, fair traveler. Meseems you have taken a daring endeavor into mono-White, hereupon I may offer some dorky card suggestions for you to consider. Shall we?

I had taken a delve into playing mono-White recently. It is far different than anything I have designed in the past, but it is something that can be toppled. You have done a fair job of this yourself, given the constraints.

A card condign of this strategy is Crackdown. It hits nothing of your own whilst being a grave hindrance to your foe. Now, your board may swing freely and dungeon crawl.

Though not flashy, Endless Atlas serves a great purpose of drawing cards, which is by far the great plight of White. Mangara, Esper Sentinel, and The Immortal Sun all bestow the same to varying degrees.

Whiles not being the most efficient, a favourite of mine has become Phyrexian Portal. This is a ball to resolve. It is like a Fact or Fiction, but around six-to-eight times worse: when one is in White, one does not care.

What if I told you there was an older and stranger version of Eerie Interlude? Thence is the lede for Ghostway. This is the way those past their day come to sway and utterly say that they shan't stay. Okay?

Do you know what is really fun to blink? Glorious Protector, for once it is exiled, it brings back everything else. This is a way to turn a Teleportation Circle into a repeatable Eerie Interlude. Though debatably worse, Lumbering Battlement gives the same.

The last recreant I may proffer is Palace Jailer. Be the sovereign and slaughter all inimical! Then you suffer one hit point and set down your crown, as is just law.

Thus is all I have for you. May fate be kind to your scale-coated leader, and may you read to the end of my comment.

If you are keen, I have two lists of my own that may be of aid to your deck-building adventures, being Orzhov Blink and Mono-White Legends. Thank you ahead of time and toodles!
