Alright, time to cover everything.
* Punch cards for counters is great. Hopefully that becomes a thing.
* Brick counters being a theme, instead of just a thing for that one card, is unexpected.
* Embalm is interesting. As for why the mummies are white, the fact that the creatures have embalm means they are probably willingly allowing themselves to be mummified, as society expects from them. I do imagine the reminder text will be quite long, but even if it was short, the nature of embalm's recursion would favor simpler abilities on the creature. It's really interesting that each embalm creature gets its own token; I wonder what this could mean for future mechanics.
* So exert really is "double tap" after all. I wonder how that mechanically fits in with everything else. It certainly doesn't have a particularly Egyptian flavor.
* Giant Spider is back!
* Tattered Mummy has the creature type Jackal, not Hound!
* Surprised the black Welcome Deck uses Raise Dead instead of Disentomb.
* Huh, so I guess the set is actually monocolor. Didn't see that coming.
* The high toughness common creatures makes me think that in addition to the other mechanics, we'll still see wither.
