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
Even without combos, its still a pretty powerful dork
This great proliferate card is fantastic in superfriends or counter decks that want to double up on their value whenever lands hit the battlefield
Uro, Titan of Natures Wrath Blue-Green is my favourite colour combination
The city's blessing isn't a permanent itself and can't be removed by any effect (well, except by Naturalize 2)
Flying Ascend (If you control ten or more permanents, you get the city's blessing for the rest of the game.) At the beginning of your upkeep, if you have the city's blessing, reveal the top card of your library and put it into your hand
