Surprised nobody's posted this yet; much less including myself. Up to date spoiler link is here, but will post more as they come in.
- Let's get it out of the way: shocks and Lantern reprints are welcome.
- Undercity Lich is almost singlehandedly making me want to build a Gitrog deck. Absurd amount of graveyard interaction here.
- Surveil seems great, especially on Dream Eater. So much value there, especially since it's a better scry.
- Glad that the obligatory 3 damage sweeper is multicolor this time around.
- Vraska's got great value for constructed: she doesn't have to sac a creature to +2, and that she can tick down twice after that is great.
- The split cards all seem fun... not sure I can judge easily their constructed appeal just yet, but we'll see!
- Also, I love new Niv-Mizzet as a commander. He's even more nutty than either previous iteration. Only thing holding him back is the color weight, but it's great that targeted removal replaces him.
