We stay on each plane for eight cards, one of each color in WUBRG order followed by multicolored, colorless, and land. So the first card in this game is a white card from Mirrodin, second is a blue card from Mirrodin, third is a black card from Mirrodin... ninth card is a white card from Kamigawa.


Planes go in the following order. If we reach the end of this list I'm open to suggestions for any planes I've missed.

Mirrodin/New Phyrexia
Kamigawa
Ravnica
Dominaria
Lorwyn/Shadowmoor
Alara
Zendikar
Innistrad
Theros
Tarkir
Kaladesh
Amonkhet
Ixalan
Shandalar (Core sets)
Fiora (Conspiracy)
Eldraine
Ikoria
Kaldheim
Arcavios
Forgotten Realms
New Capenna
Thunder Junction

Strength of Steel -
Instant
Creatures you control get +1/+1 until end of turn. If you control an artifact creature, draw a card.

That's what I get for speed reading.

Reset
Instant
Affinity for artifacts
Untap X target permanents.

Needs to be a blue Mirrodin card YingLung

Dross Hopper -
Creature - Frog | C
When Dross Hopper enters the battlefield, create two colorless Cog artifact tokens with “Sacrifice another Cog, : Draw a card. You lose 1 life.”
2/1

Cool idea!

Arc Shock —
Instant (C)
You may exile the top ten cards of your library rather than pay this spell's mana cost.
Arc Shock deals 2 damage to any target.

(I'm sure this is broken, but changing any of the numbers would have ruined the flavor)

Phyrexian Hydra -
Creature - Hydra
~ enters the battlefield with X +1/+1 counters on it.
Infect
0/0

Mirrodin, and no option for colorless? Shame on you.

Four-Tails Blademaster
Creature - Fox Samurai
Bushido 4
2/4

Let's try this again

Divine
Sorcery - Arcane
Scry 1 and return Divine to your hand.
Splice onto Arcane

Cute game idea.

Ruthless Shinobi

Creature -- Rat Ninja (U)
Sacrifice another creature: Ruthless Shinobi gets +2/+2 until end of turn.
Ninjutsu
2/2

I think this game really should have the standard multicolored, artifact, and land stages that most of these games have. It feels weird to design for planes like Mirrodin and Ravnica without having those. Sounds like a fun game, though.

Bound Oni
Creature - Demon Spirit (U)
Haste, trample
At the beginning of each end step, sacrifice Bound Oni unless you control an Ogre.
5/5

Agreed. Can we make it WUBRG, multicolored, colorless, land?

Serene Meditant

Creature -- Human Monk (R)
If a player would draw a card except the first one they draw in each of their draw steps, instead that player skips that draw.
"You know what you were meant to know. You are what you were meant to be."
2/2

Ami, Artisan of Clouds
Legendary Creature — Moonfolk Wizard
Flying
, Return Ami, Artisan of Clouds to its owner's hand: Copy target instant or sorcery spell you control. You may choose new targets for it. (The copy keeps all spliced text.)
"The cold calculus of our ancestors neglected the cost to their souls. Beauty is its own reward."
2/1

Samurai Sword
Artifact - Equipment (U)
Equipped creature has bushido 2.
Equip

Chapel Chaperone

Creature -- Human Cleric (C)
Vigilance
Prosper — Chapel Chaperone enters the battlefield with a +1/+1 counter on it if you've gained life this turn.
He guides worshipers to the pews that best fit their price range.
2/2

Edit: Whoops, land. How easily I forget.

Reikai Gateway
Land (C)
Whenever Reikai Gateway or a Spirit enters the battlefield under your control, gain 1 life.
: Add .

Matter-Scatter Pathing
Instant
Up to two target attacking creatures can't be blocked this turn. If this spell was jump-started and it has two targets, return one of those creatures at random to its owner's hand.
Jump-start
"Interesting. Write up a report and deliver it to me personally. Tell no one. This project is now classified." — Ral Zarek

Back-Alley Murder
Sorcery (C)
Destroy target creature an opponent controls. Target creature you control gains menace until end of turn.
In Ravnica, when you hear a cry for help, you run the other way.

Fire Eater
Creature-Elemental
Whenever Fire Eater would be dealt noncombat damage, it gets that many times +1/+1 until end of turn instead.
2/1
Nobody knows where they came from, but the League's mages had no trouble getting them to stay.

Transplant
Sorcery
Put a basic land you own from outside of the game onto the battlefield.
Dryads range far and wide across the city, seeking out new seeds for their gardens.

Shoot the Messenger
Instant (U)
Counter target noncreature spell. Its controller sacrifices a creature.
"I'm sure he would have stopped if I'd asked, but killing him was so much simpler."
