Here is the link to my original Mono Shadow deck

After getting into top 100 I hit a big wall. So I posted my list here and got some advice and was able to hit top 50, then stopped playing and am currently sitting around 69 due to the break. I feel like this deck is one of the best decks in the format. You have a great answer to everything while having some of the best threats we have ever had. I wanna talk about the new card choices from the original deck I was playing.
Damara, Deft Saboteur - Great card that doubles as pressure and removal. If I'm playing against control I'll hold of til I can ambush then activate the ability and take the best card from my opponent's market. Against aggro it is a great removal card that trades with everything in it's same power cost.
Makkar's Quiver - Best card in the deck. Removal and game ender. I wasn't a believer until I played it. Once I did, it changed everything about how I built the deck. Do not leave home without 4 of these bad bois.
Incarnus, Makkar's Listener - Also a busted card. Auto replaces itself, combos so well with Quiver, and closes games fast. Play 4 of.
This deck has very few losing matchups. Honestly, with the nerf of FTS, I think this deck is the best deck in the format right now. Will do a write up later for y'all!
this deck looks great, my only consideration would be maybe subbing Marionette for Auric Interrogator. Hes an easier removal target in expedition but it may be a way to sneak more card draw into the deck with makkar.
