Kamigawa: Neon Dynasty

Sagas - As long as the saga or the flip side does not search the library or have an otherwise awkward interaction with your cubelet, they are pretty interesting includes because of the fact that they transform into a creature.

Reconfigure - The mechanic as a whole is very cool and could make for a sweet thematic cubelet. Cards mentioned below with Reconfigure are the highlights that could be included in any cubelet.

Ninjutsu - The mechanic as a whole is very cool and could make for a sweet thematic cubelet. Cards mentioned below with Ninjutsu are the highlights that could be included in any cubelet.

Invoke Cycle - They all do some very sweet things at 5 mana. Rather than highlight each one, let's just say they are all good!

​Dragonfly Suit
The crew 1 makes it very accessible and a flyer usually requires an answer from the table.

Farewell
Has a pretty big cost, but with it, some pretty great power in removing most problems all at once from the game.

Hotshot Mechanic
Pretty great if vehicles are a theme to your cubelet. A 2/1 artifact creature for 1 also helps delirium strategies as well.

Imperial Recovery Unit
Even getting one creature back seems great. Another fine vehicle to consider

Kyodai, Soul of Kamigawa
Might be a little too strong late game to make an 8/8 flyer, but the interactions early game seem fun.

Lion Sash
If you share the graveyard, this is a nice little guy to clean things up, also pretty neat equipment

Lucky Offering
If you are suddenly adding a bunch of vehicles or cards with reconfigure, this is a possible solution to keep it balanced.

Mindlink Mech
There are usually a lot of interesting creatures in the cubelet, so copying them when you crew seems fun.

Mnemonic Sphere
If you're having problems getting delirium, this is an exceptional card to consider.

Mobilizer Mech
If vehicles are the game, this is a great way to help grind things out.

Biting-Palm Ninja
The "free" choice to potentially exile a problematic card is pretty great.

Blade of the Oni
Good stats all around. Hard to not consider it.

Dokuchi Silencer
The ability to destroy someone's planeswalker if you connect with Ninjutsu is something worth considering if you run planeswalkers in your cubelet.

Junji, the Midnight Sky
A lot to handle, but if the cubelet is built to contain a bomb like this, the run with it!

Mukotai Soulripper
Pretty neat card, as you have creatures that lose their "oomph" you'll definitely get some good value by sacrificing them.

Nashi, Moon Sage's Scion
You only have one library, so you get basically a free card at the cost of life once you hit a player.

Soul Transfer
Neat card with choices and if you happen to meet the conditions to choose both, sweet!

Tatsunari, Toad Rider
Neat effect if your cubelet is built around enchantments.

Lizard Blades
Fun way to give your creatures double strike.

Rabbit Battery
Fun way to give your creatures haste.

Simian Sling
One-drop cubelet might enjoy this monkey.

Spinning Wheel Kick
Obviously gets better later in the game, but a bite effect that can target multiples seems great.

Invigorating Hot Spring
Pretty neat enchantment. Removing a counter only once per turn seems pretty fair.

Prodigy's Prototype
Nice effect, good to help support a vehicle subtheme, the versatility to crew bigger vehicles with the token also nice.

Tamiyo, Compleated Sage
Of all the planeswalkers, this is the one that seems the most reasonable to play around with in cubelet.

Brute Suit
A heavy beater and decent to trade up in blocks.

High-Speed Hoverbike
Flash is a nice edition to an otherwise fine 2/2 flyer.
