Here's what I've got, currently 7-3 atop the iOS ladder with two of those losses down to flood and screw. Resolving a Monument again control is one of the more satisfying things I've found in duels- it looks like innocuous jank, and they don't realize till later they died t3.

Cinder Barrens This is more focused on chaining than Haven's, going max monuments and no straight discard (love those Condemned though Haven) to get to the next piece in a hurry.
Early game is all about gentle pressure through Neonate/Siphoner/Copter, ideally with a monument T3 then starting the chains T4.
Waltz is fantastic and I don't know what you all are talking about. a couple madness vamps in the yard midgame with monument in play and you're getting at least 4 cards out of it; it's a huge momentum swing and it really allows you to swing carelessly with those Bloodmads early on, or pitch creatures to loot that you'll want back later. You churn through enough deck that 2 is plenty, but they're both monsters.
Glorybringer & Gearhulk: don't forget monument also just lets you play wincons a turn early. Gearhulk is fantastic; either dealing damage from pricy madness cards and feeding your next Waltz or giving you your next chain straight up.
Never: this has also been a Sinister Concoction and an Unlicensed Disintegration for me in testing, but right now I'm seeing more Walkers than Harvesters on my ladder, plus it can be a moderately useful discard target.
Major play notes: the chains all go on the stack, so they resolve backwards. This means if you start a chain with Olivia you don't get to use her ability on any vamps you chain off her. It also means if you finish a chain with a Fiery Temper to their Thalia, say (just did this while wrecking Orzhov midrange goodstuff), all your stuff comes in untapped.
Most importantly, it can be really tempting to loot away all your land, but you really want to make a drop every turn. You can't really get huge chains going if you only have 5 land, especially once you start adding big creatures or Waltzes to your operating costs. So if I don't have an immediate land drop, I'll start a chain on my turn to dig for one rather than wait to do it at the end of theirs, unless I'm really certain they're about to sweep. Prioritize red; 2-3 black sources is generally plenty for a game.
