The thing is, you dont know what youll get, and because its EDH, maybe those cards dont help your strategy or what youre doing at all
Haunted Mansion does not, however, stop cards from banishing themselves as a cost to activate effects, nor does it stop Spells/Traps from being Set from the Graveyard (Toadally Awesome and Terrors of the Overroot can do this)
sometimes it is just game over but equally it can be a complete do nothing
Some of them see occasional play in Standard and/or Explorer and Pioneer, but they have been pulled back enough not to make them overwhelming, but at the same time they are in some cases in a poor place where they are overly strong in limited, but dont do anything in constructed
If we compare it to both Battle Styles and Chilling Reign, Evolving Skies is by far the most valuable expansion of the year so far
We also saw some Commander stuff in the preview, including four Planechase cards
