Duskmourn should be banned.
It ruins Standard. The cards in the set are broken, and it's not just Leyline of Resonance that should have been banned, it's the whole set. Screaming Nemesis, shouldn't be able to target players if there's creatures on the board, that's ********. There is no flavor to this set, it enables boring and lame play styles to the max, such as milling your opponent to death, or basically being able to kill your opponent with Screaming Nemesis because he just blocks with it, kind of ruins the balancing of Standard.

Well, Standard was broken after the release of Outlaws of Thunder Junction due to the multiple blind insta-kill combos (e.g. Rush of Dread + Bloodletter of Aclazotz) and uber-aggro cards like Slickshot Show-Off.
Bloomburrow only continued the mega-aggro meta with Manifold Mouse and Stormchaser's talent.
Offensive mill decks were actually worse a few releases ago, but I've always felt the mechanic shouldn't exist. It's kinda' obvious, but players want to play with the cards in their decks. If they can't do that, it's not fun. WotC at least greatly toned-down land distruction (which has the same indirect effect). They should further decrease offensive mill. Self-mill is fine.
Leylines were always a bad idea, but Leyline of Resonance should've been banned after the first few weeks of play. It was, eventually, banned in all Bo1s, but that's just a horrible card policy to begin with. No card should be banned from a "match style". If WotC wishes to go down that road, they should adopt a "points system" like Highlander for Standard.
I disagree with Screaming Nemesis as there are many ways to deal with it--either with cheap type-changers (e.g. Unable to Scream) or non-damage elimination (Get Lost, Candy Grapple).
Another concerning trend are cards that have "percentage" (halving, doubling) effects against finite (non-percentage) resources such as Unstoppable Slasher, Tifa Lockhart, and Mossborn Hydra. They're just rife for abuse, format-warping, and promote generally un-fun gameplay.
Finally, there are cards like Bloodthirsty Conqueror which are fine on their own, but have bugged (as in not following the rules of magic) combo implementations on Arena. These cards should be temp-banned until the implementation works correctly.
Overall, I have no hope for "generally fun Magic in Standard" until the Fall rotation.
In the interim, I just play knowing I'll insta-concede about 1/3 of my matches against non-interactive (unfun) decks, bugs, grossly off-format (80+ card decks in a 60 card format) decks, or known-bad players.
