Requiem of a Nightmare (Modern)

Grixis midrange deck with a flexible gameplan. It can be particularly aggro with burn spells, but can also reanimate creatures with strong effects that facilitate consistent spell playing or enhancing your board. Snapcaster can abuse burn spells, utility spells like unearth for Lightning Skelemental or Seasoned Pyromancer, but can also consistently interact with an opponent's hand-- all while synergizing with Thing in the Ice as a pseudo-board wipe.

With the banning of Faithless Looting, I incorporated Seasoned Pyromancer because he's essentially a FL on a body. He's also just great for discarding Lightning Skelemental on ETB to get tokens and you could still Unearth LS same turn. I put in a two-of for Pteramander as a good way of keeping the mana curve down after adding SP and chose it over Young Pyromancer given the flying keyword ability and how many spells will be in the graveyard (I also just think YP is pretty underwhelming when compared to Thing in the Ice).

Biggest weakness at the moment is Leyline of Sanctity since all of the CMC1 spells are "target" spells and Leyline of the Void since it can negatively impact graveyard interaction (though this is not as crucial in this deck since the spells are strong on their own). Ratchet Bomb might be slow but it'll wipe Leyline if needed and you could still lean into burn damage while it's out. Engineered Explosives is great catch all for Modern in tri-color decks.

Lastly, I considered Thoughtseize over Inquisition of Kozilek since it's just straight up better, but tri-color decks are notorious for needing lots of fetches/shocks in the early game.
