I will admit that I prefer more aggressive play as opposed to a slower, more control heavy style, so that may influence my choices, and I've also been (partially) traumatized by a few planeswalker decks before, so I don't really like them that much (although I do like the concept and design of them)
Im only including this here because its sometimes relevant in Eternal formats besides Commander
Thankfully, you can combat foil curling if you need to fix a foil that was not sleeved or stored well
Jump Scare's main focus is on taking full advantage of the manifest variant called manifest dread, which acts just like manifest in that you put cards onto the battlefield face-down as 2/2 creatures
I do believe, though, that design is in a healthy place, and that we're continuing to improve our ability to make awesome Magic sets
