To this day I actually haven't played against a proper "Monument" deck so I don't really know the Meta around it but when I thought about the new sweeper Settle the Wreckage I immediately thought of this janky idea to attack and exile a ton of my own creatures to drop a ton of land onto the field and thin my deck and then be able to just barrage the board with tokens again.
Probably not worth it, however, using it against a wide strategy and combined with Aven Mindcensor so they can only look at the top 4 cards for land instead of their whole library suddenly makes Wreckage kind of sweet.
I pretty much went with a ton of cheap white creatures, a real grab bag of stuff. The idea is to drop them cheaply to create more tokens that eventually get out of hand because of
Annointed Procession
and all that lifelink ensures one or two free 5/5 Indestructible Horse Tokens every turn from your Crested Sunmare. Yee-haw!
The rest of the deck is literally loaded with isolation cards like Angel of Condemnation, Angel of Sanctions, Cast Out, and Ixalan's Binding.
Kinjalli's Sunwing adds even more shenanigans by making your opponent's creatures come in tapped. Annoying.
Then you've got Regal Caracal which is nuts with
Annointed Procession
as are all of the token generating cards which is basically everything.
There wasn't nearly as much thought going into this as I normally would, but it just sort of jammed together this pretty nice ball of rubber bands that work out somehow. Sometimes that can be powerful on it's own by keeping your opponent guessing as much as you are.
The sideboard has a bunch more control effects that hope to shut down a variety of strategies using cards that shut off entire mechanics just by sitting there. Ashes of the Abhorrent says "No to Graveyards!" Tocatli Honor Guard says "Down with ETB effects!" Solemnity says "Screw you Winding Constrictor, Verdurous Gearhulk, and Walking Ballista!" Sorcerous Spyglass says "No you don't, you... thing!" You get the idea.
That's pretty much it. A mono-white deck that does a little bit of column A and a little bit of columns B through Z.
