One line explanation - Controly-Midrange with Gifts Ungiven to fetch "thing" and Unburial Rites
Card choices.
Lands
Celestial Colonnade - 4/4 Vigilant Flyer landing mid-late game is nice.
Flooded Strand - Fetches out Hallowed Fountain, Temple Garden and Watery Grave (plus basics)
Ghost Quarter - Hate against tron lands, and manlands.
Poluted Delta - Fetches out Hallowed Fountain, Overgrown Tomb and Watery Grave (plus basics)
Creatures
Grave Titan - Value machine late game, if it sticks it will do a lot of work, testing it out post Splinter Twin banning.
Iona, Shield of Emeria - Target for Gifts Ungiven, is good card.
Jace, Vryn's Prodigy
- Cycle through to hit cards I need, and can dump Iona/Winnower into the graveyard if I draw into them.
Snapcaster Mage - Recycle my spells, and also if I search for two spell that do the same thing + Snapcaster I will get one of them.
Void Winnower - Serves a similar purpose to Iona.
Instants
Abrupt Decay - Removal, hits all the good stuff (Blood Moon, Liliana etc).
Cryptic Command, Logic Knott, Mana Leak and Remand - Counterspells.
Gifts Ungiven - Can use to search for "combo" of Unburial Rites and Iona/Winnower, oooor it can be used to search for Boardwipes/Removal/Counterspells in a pinch.
Shadow of Doubt - In response to a fetchland is funny, basically 2 mana land destruction cantrip in modern, also useful against Chord of Calling etc.
Sorcerys
Day of Judgment, Wrath of God - 2 different types so I can fetch them with gifts and a snapcaster.
Inquisition of Kozilek, Thoughtseize - Similar to the wraths above.
Unburial Rites - "combos" with gifts to get Iona or Winnower onto the field quickly.
Sideboard
At the moment im in a very mixed meta so the sideboard isnt very tuned very well.
Abrupt Decay - Side in against ,Blood Moon, AEther Vial, Jund, Merfolk
Celestial Purge - Blood Moon, Liliana
Elesh Norn, Grand Cenobite - Against creature heavy strategys (Zoo, Goblins, Tokens, etc)
Empyrial Archangel - Against Burn (In Testing)
Flaying Tendrils - Tokens, Soul Sisters.
