Hello, everyone. This is a new concept for a plane, and I need some help designing for it. If the concept intrigues you, feel free to contribute however you see fit. Any help is much appreciated.
The setting is Mundara, a crystalline world that spirals in on itself--trapped in a perpetual cycle that lasts eight days. Within those eight days, six are spent on the surface, where the sun is visible, and the land can be seen from the Blind Eternities. However, the other two days are spent spiraling down the center of the world--two days in the inky darkness of the Maw, where death rates skyrocket, and the consumed regions are riddled with paranoia. Beyond this cycle, the shifting world clears a path for amazing breakthroughs, along with devastating calamities. Entire cities have been swallowed by the world, only to resurface several decades later. Lost artifacts and missing pieces of history seem to unearth themselves after disappearing for millennia. These random occurrences leave everyone on the ground at risk, and very few are lucky enough to fully escape the dangers of Mundara.
There are five main regions of Mundara, along with one unmoving landmark.
Tixalni is mostly associated with the c, and is a technologically advanced paradise consisting of floating islands. (Ink-Treader)
Puntarr is heavily forested, and its reaches are dotted with small tribes, each with their own notable attribute. (Glint-Eye)
The Nagashim is a river that circles around the world multiple times, but it is never completely necessary to cross it. (Witch)
Loku is a mountainous region, mostly known for its two warring families. (Dune)
Phantirda was once a fertile region, but it has recently devolved into a wasteland. Two great necromancers inhabit Phantirda. (Yore)
The Maw is a giant hole through the center of Mundara. Each part of the world spends two days in the Maw out of every eight. (Chrome)
This set is a 'four-colours matters' set with 'bottom of library matters' secondarily. There will be four or five mechanics in total, and one of them will be cycling. I will update this as time goes on and more ideas are bounced around. Thanks to all who contribute, and have a wonderful day!
Cycling: /cost/--Discard this card, draw a card.
Spiral: At the beginning of your upkeep, reveal the bottom card of your library and put it on top. (Credit to @MagicChess
