Hello everybody! Not english-speaker here, so be kind please.

I started working on my personal list as soon as the first video appeared on the web. I designed a cube before and i am a big nintendo fun, therefore the whole project is super appealing to me. I started with few cards just for fun, but now i find myself with a very big list of designed cards, a crunchy/math balance of CMC and color spread (not perfect, but work as a starting point) on the number of the cards i want in the set and the right number i want to support each archetype. As a designer, i try to reach flavor with as few words as possible, since cards should be easy (as easy as the existing one) and not too much convoluted, otherwise they won't work together (i'm proud of the result of my version of Piranha Plant for example).

For all of you out of there, i found many compelling artworks that could be used for your cards and most of them have been credited (sometimes i find asian artists that i am not able to credit or long rabbit holes of linked images between many web sites). Use the card list as a useful list of nintendo fan arts to use for your future cards.

The following is my super-messy working document: https://docs.google.com/document/d/16EyBYucyJTfMSIqYcNbiPAcV6rPRKnOw2V6fr2awlBA/edit?usp=sharing I allowed to everyone to add comments, be respectful.

In my project, i gave different themes to the shards.

• Bestow is a mechanic from Theros that i brought back on the card of the set since it works very well with Super. Yoshi's are very common bestow creatures (possibily sacrificed by Super or surviving if Mario is removed otherwise). I tried to limit myself to as few returning keywords (excluding the evergreen ones) as possible.
• Grixis (uBr) and Jund (bRg) are still associated with Boos and Bowser's Koopa Troop respectively, with no change on the keywords. For flavor, Spawn create tokens of different colors, so that it's possible to have different color minion tokens (a small boo one in black, a koopa in green and a goomba in red).
• Bant (gWu) is the Mushroom Kingdom shard. I moved Super to white and there are interesting auras/heroic-like effects in green and blue.
• Esper (wUb) is the Cosmic Realm, centered around Rosalina and Stars. The basic keyword is designed around Rosalina's Storybook and is a slight variation on Transmute (Turn the Page allows to discard a card for tutoring a spell with 1 CMC higher)
• Naya (rGw) is the Kong Island shard, centered around Donkey Kong and co. The main keyword is collect (since donkey kong games are collectathons) that work as a keyword action to create treasure tokens. It's ramp in green based around treasures.
• In white there are some Mario Kart cards and in green some Mario Maker cards, but i don't think there is enough material (and good artwork!) to support the theme for the whopping amount of cards required in a shard.

After having prepared all the cards, i will start refining all the effects to allow the support for all the archetypes. The effects written here are just the first version, i'm still refining them.

TL;DR

THIS is my working document for the personal Mario cube i'm working on. Have fun!
