Been doing a lot of deskwarming these past few months. Leaves me a lot of time for theorycrafting decks I haven't played for formats I've barely played. Also should probably mention that this is mostly cannibalized from FTW's dimir lantern list (the manabase ratios in particular) and thnkr's lists on mtgsalvation forums. That being said,

//Artifacts: 22
4x Lantern of Insight
4x Codex Shredder
2x Pyxis of Pandemonium
4x Arcum's Astrolabe
4x Mishra's Bauble
3x Ensnaring Bridge
1x Pithing Needle

//Instants: 6
3x Assassin's Trophy
3x Surgical Extraction

//Sorceries: 14
4x Ancient Stirrings
3x Scheming Symmetry

3x Thoughtseize
3x Inquisition of Kozilek
1x Collective Brutality

//Lands: 18
4x Prismatic Vista
4x Verdant Catacombs
2x Snow-Covered Forest
2x Snow-Covered Swamp
1x Blooming Marsh
3x Ghost Quarter
1x Inventor's Fair
1x Academy Ruins

//Sideboard:
1x Assassin's Trophy
1x Nature's Claim
1x Surgical Extraction
3x Collective Brutality
3x Pithing Needle
2x Welding Jar
1x Grafdigger's Cage
3x Leyline of Sanctity

Went with GB for Trophy and Stirrings. Whir is great but 3U is tough.

Went with fetches and snow lands and Astrolabe and whatnot. Might be wrong for a 1-color build, maybe no Astrolabe and 4x Glimmervoid is correct (it's definitely more correct for my wallet). Especially since Astrolabe is my only blue source for A. Ruins, which is probably bad. On the other hand its an artifact that mana ramps and cantrips, idk.

3x GQ and 3x Surgical 3x Trophy main could go out for other stuff for sure. I just like GQ for the tron matchup and being able to mill a wincon and then surgical it has been a big draw of this deck for me. Total timmy reasoning I know.

The discard spell ratios can also be whatever as long as theres 6-8.

Ignore the sb, will probably be tailored to my local meta anyways. Whatever my local meta is. Haven't really had the chance to go to fnm due to covid and whatnot.
