Oh, this got bumped up. I suppose I'll post that big post I was working on that I decided not to post when this topic wasn't getting much activity.
Like I said I would, I'll post some recent Magic stories I liked. This turned out a lot longer than I intended, so I'll just put a few at the top, then the others will just be recommended for those interested in more.
Ajani, Mentor of Heroes (About a lion-man, or leonin, planeswalker named Ajani coming to the Greek-inspired world of Theros)
Summary of Theros e-book, needed to understand the next story
Ajani's Vengeance (What Ajani does after the events of the e-book)
Kruhpix's Insight (Epilogue to the Theros story)
The Hunter Cannot Pity (Story of a planeswalker from the birth of his powers to his death, ties into the Garruk story)
Monster (Notable for having Garruk beat up Jace, who is simultaneously the most popular and most hated character in Magic)
The First World is the Hardest (Origin story for a villain named Ob Nixilis)
Don't quite remember how good they were, but had positive feelings when skimming over for this post:
In Praise of the Worldsoul,
part 2,
part 3 (Takes place on Ravnica, a city-world ruled by various guilds; features interactions between Selesnya, Gruul, and Rakdos guilds)
The Seven Bells,
part 2 (Takes place on Ravnica, about Izzet mad scientist shenanigans, format is borked from transfer to new site)
Gruul Ingenuity (Takes place on Ravnica, about a Gruul fighter learning new magic, has a preview card)
The Absolution of the Guildpact (Takes place on Ravnica, about Boros guys watching a play about the events of the first Ravnica story, has a preview card, links are borked)
Persistence of Memory (Takes place on Ravnica, about Dimir intrigue)
The Burying,
part 2 (Takes place on Ravnica, origin story for Domri Rade, a Gruul planeswalker)
The Guild of Deals (Takes place on Ravnica, about a guy being dicked over by the Orzhov guild)
Expectations (Takes place on Ravnica, semi-sequel to Persistence of Memory, about Azorius and Dimir guilds)
Life in the Ring (Takes place on Ravnica, about the Rakdos guild, notable in that it's one of the few stories where they actually come off as noble)
Preparation (Takes place on Dominaria, I think, which was the main world for early Magic; about Jhoira)
Zurbit's Day (Unknown plane, notable just for the ending involving a cat)
Stories I remember were good:
The Lost Confession (Takes place on New Phyrexia, described in my earlier post; about Elspeth and that place)
The Consequences of Attraction (Takes place on Theros, a Greek myth inspired story involving a woman getting screwed over by a god and turned into a siren)

Dreams of the City (Takes place on Theros, sequel to Building Toward a Dream)
Nissa, Worldwaker (Takes place on Zendikar, about Nissa fighting Eldrazi, has a preview card)

Sorin's Revelation (Takes place on Tarkir, about Sorin investigating the plane, has a preview card)
