Everything in the Jump Scare! Commander deck: all 100 cards with current prices, what the deck is worth against the sealed price, the 10 new cards, and whether it is worth buying.
Landfall — Whenever a land you control enters, manifest dread if this is the first time this ability has resolved this turn. Otherwise, you may turn a permanent you control face up. (To manifest dread, look at the top two cards of your library. Put one onto the battlefield face down as a 2/2 creature and the other into your graveyard. Turn it face up any time for its mana cost if it's a creature card.)
I’m usually not a fan of the “GUx ramp deck” that seems to come in every collection of Commander precons. I had this gripe with the Tricky Terrain deck from Modern Masters 3 Commander, where it had a really cool premise that was overshadowed by the typical Simic ramp stuff we see all the time. Jump Scare! does that a little, but I think the commander is very novel and the manifest approach makes it feel distinct. There’s a lot more customization options for a deck like this that differentiate it from a typical Simic ramp deck, which I appreciate. Overall, I’m a fan.
Logistically, the value of the deck is almost entirely tied to two cards that’ll likely tank in price, though having those reprinted is a big deal. The mana base is noticeably lackluster. It’s functional for precon purposes, but I’m continuing to dock points for lousy precon mana bases.
Zimone, Mystery Unraveler
Jump Scare! Is a Simic ramp deck with a face-down creature component. It’s looking to spend the early turns accelerating its mana, after which it can either cast giant green battlecruisers or hopefully manifest a few creatures to jump scare your opponents with. It makes good use of the new manifest dread variant and incorporates some light morph elements.
The face commander is Zimone, Mystery Unraveler, a pretty straightforward Simic card that uses landfall as a way to manipulate face-down creatures. Honestly, it’s a pretty cool take on a Simic commander, and I like that you’re capped at one new manifest per turn but still rewarded for subsequent landfall triggers.
Kianne, Corrupted Memory is much less exciting, though the toggling between flashing in creatures and non-creature spells is interesting. It’s a draw spell payoff with no inherent ways to draw cards, though having half a Vedalken Orrery in your command zone at any given point could be powerful.
Simple. Let’s add in all the sick face-down-matters cards in Simic colors we can find and cull everything else that doesn’t synergize!
