I got some feedback from Aqua that I needed to offer a bit more in the control department as well as a bit more in the B aggro department, so here is a list of swaps and "possible adds" for later on down the road. I like the idea of increasing the amount of Instants and Sorceries too, especially for Young Pyromancer, Talrand, and the Tazeem Roilmage/Ghitu Chronicler shenanegans. More long term goals, I want to increase the amount to black fetch lands while reducing the amount of black "comes into play tapped" lands, to feed a more aggressive tone.

Iridescent Drake > Exclude: Iridescent Drake was originally included as part of a 3-Piece Combo (Abduction and Altar of Dementia) but there is no crossover into ANY archetypes for the drake and the aura, (completely unplayable) so they are getting nixed. Altar is staying as there is a lot of crossover with other archetypes and combos

Abduction > Desertion: Abduction only works in combo and isn't strong enough to hold on its own, while Desertion is a SCARY counterspell that allows for some wild mind games.

Sengir Vampire > Festering Goblin: Tough to cut the nostalgic Vampire, especially since I wanted a home for the sweet Beatdown foil and art, but there is no crossover into any archetypes and I like the idea of reducing the average power/toughness of the cube to help let the Kavu tribe shine a bit brighter. Festering Goblin has a lot of crossover into Goblins, Zombies, Deadguy Ale, Machine Head, and mono B aggro. Plus I have an Onslaught foil from 20 years ago that was shuffled sleeveless for many, many years.

Bladewing the Risen > Brine Shaman: I think I can safely give up on the dragon archetype in this cube and I don't want to give players any false-hopes. Making this swap softens the cube's mana requirements, and caters to more of the cube than the 7cmc dragon. Brine Shaman allows for stacked damage exploits, big control lockouts, and is also a Cleric which needs a bit more support.

Engineered Plague > Carnophage: The tribal hate card gets last picked very frequently and doesn't cater to any of the cube's synergy other than punishing players who lean into the cube's synergy. It's pretty underwhelming when next to Plague Engineer (which I might even add a second copy of later down the road). Carnophage carries a lot of nostalgia and also contributes to a more aggressive/reckless identity for black than the controlling enchantment

Scalding Tongs > God-pharaoh's Statue: The one damage from tongs is pretty lackluster, meanwhile I've always loved the old school feel of God-Pharaoh's Statue; it's WAY more powerful than Rain of Salt but is way less of a feel bad on the receiving end for some reason. I'd like to increase the average CMC of artifacts to help make Karn, Silver Golem a bit more playable too.

Drain Power > Circular Logic: I thought it'd be nice to give Drain Power a home in an environment where it might be able to live again, but this card just plain sucks. Adding a second copy of Circular Logic back in the pool as another counterspell with a lot of crossover.

Frantic Search > Remove Soul: I don't was to mislead any drafters in thinking there is a storm archetype in this cube. Frantic Search was just a wholesome looting spell and when there are almost no ways of making the spell cheaper or making your lands tap for more mana, it ends up becoming a bit of a trap. Remove Soul will be more powerful than most due to the high amount of creature spells in this cube. Plus it's white border.

Glacial Chasm > Spiketail Hatchling: Glacial Chasm is a card that is TERRIFYING to newer and more casual players. The only people who are going to draft it in this cube are oldschool, sadistic players who want to break the extreme drawbacks of the card (that's me, not gonna lie). It can only be played in a prison/lockout archetype and its narrowness also gets it voted off the island. The subgames that Hatchling contributes to are fun and it increases the amount of counter magic in the cube.

Pauper's Cage > Thran Dynamo
Wheel of Torture > Portcullis
Cutting both of these cards as they just straight up aren't The Rack. Both Pauper's Cage and Wheel of Torture are control cards and that are much worse at control than Thran Dynamo and Portcullis. At first glance, they look like aggro cards, since The Rack is such an aggressive card, but they never play out that way. Dynamo and Portcullis also have a higher CMC to increase the playability of Karn, Silver Golem

I just placed my order for the new triomes and a few other cards for the Dumpster Cube, but I forgot to order a copy of Sarcomancy (which I need for NeoPreModern) so hopefully me typing this out right now helps remind me next time.
