Wander in death is an effect they usually cost at 3B and you can cycle it. Seems entirely playable to me especially with so much support for self-mill.
Sometimes people pump before blocking, and EOT cycling is worth another 1 mana.
If we're getting into sorceries I'd rather play something with a spell with "can't block" tacked on (like that LD spell), or a global cant block.
Monster is solid but boring. Since most red damage spells deal 3 it's not amazingly amazing compared to the many 3/2 for 3U. Transmuter is also a fun combat trick and on the turn you play it kills any creature with 3 toughness or less, often without itself dying.
The Owl is just bad. Too many better 3/3s for 5 with flying.
The barrier is pretty interesting. Probably borderline. It's either a combat trick or it nullifies two attacks or what have you. Most -X/-0 spells aren't good enough. Dismissal in a cube that can include the old counterspells isn't good enough. By the time you have spell mastery you might not be able to actually counter anything.
Unburden is probably the best one thanks to the cycling since discard two can be a dead draw mid and late game. Also it wins some sort of award for "art doesn't really have anything to do with the card".
Stab wound is awesome. Either you kill a dude or you slap it on a wall or a 2/3 or something and it becomes your win condition. If you have fliers slap it on a ground pounder (best if it's a wall so they can't keep attacking with it) and attack in the skies. In RTR draft I've killed people from 20 with stab wound. It's a really strong card.
It's actually good news that a lot of slivers got downgraded. Makes it easier for me to have slivers in my cube, even if some of them will have the silver symbol.
Saga cycle lands aren't worse than Onslaught ones. You can cycle off-color saga lands if you need a 23rd card. And sometimes you have one swamp and five mountains and don't want to tap your swamp.

The new dog soldier guy in KTK gives all dudes with +1/+1 counters first strike. So reveler is a 3 mana 3/4 first strike. Sexy.
