Just trying out a few cards I got at Tarkir Dragonstorm prerelease.

Descendant of Storms: A 2/1 for 1 that can act as a mana sink, either growing your board or itself, I think this would fit well in this cube. Dryad Militant will go in the pile of cards for a possible graveyard focused cube I'm working on.

Sunpearl Kirin: I like the flexibility here, and the art's nice. I quite like whitemane lion style effects. There's enough non-humans that I wasn't super happy with the lieutenant, but it could certainly come back in the future.

Static Snare: Love the flexibility that flash gives this. On the attack, white goes wide enough that this will often be a single mana, and on defense it's often going to be not much worse than the Not on My Watch that it's replacing. I don't care for the swinginess that can come from banishing light effects, but I want to give this a shot. I'm not super confident on NoMW returning in the future, but maybe it could happen.

Sinkhole Surveyor: I like endure as a mechanic and want to try this guy out. Originally I was going to cut rotting regisaur for this (Reggie doesn't fit this environment, he'll get kicked upstairs to the Make Waves cube at some point) but I realized Dreadhorde Invasion is a closer comparison, and I want to move that over to the Trinket Cube anyway to get another enchantment that makes tokens over there anyway, so that's the swap.

Magmatic Hellkite: Pyre Hound was always in here as a placeholder until I found something I wanted to test here, and I have found that this in Hellkite. Oftentimes this is probably just blowing up a dual land to make the opponent's mana a little worse, but it might hit a creature land occasionally, so that's cool. We'll see how it does.

Cori-Steel Cutter: I enjoy the minigame that flurry cards give you by encouraging double spelling. Cutting Etali's Favor because I don't enjoy the randomness of discover in this environment, it'll get kicked upstairs to the Make Waves cube. Looking forward to this one in some sort of tempo deck.

marking a few possible cuts, mostly things I'd kick upstairs to the make waves cube whenever I get that built

marking some things I might cut in the future

it's only almost 10% of the cube being swapped out, don't worry about it. Cutting the ninjas subtheme from UB to move it to another cube I'm working on. Adding some more support to the UG flash theme. Removing the artifact matters stuff to move to the Trinket Cube. Various other miscellaneous changes.

Golgari considerations

the last change shows in the blog post but didn't affect the actual list?
