MTG Salvation

Six, Dryadic Engine
Legendary Artifact Land - Vehicle Forest (M)
(Green Color Indicator)
(Six, Dryadic Engine isn't a spell and it has "T: Add G."))
Crew 2 (Tap any number of creatures you control with total power 2 or more: This Vehicle becomes an artifact land creature until end of turn.)
Six, Dryadic Engine doesn't untap at the beginning of your untap phase.
If Six, Dryadic Engine is a creature it has "Remove a Loyalty Counter from a Planeswalker you control: Untap Six, Dryadic Engine."
6/6

Essentially what I'm trying to do. But . . .

Black - Morbid
Red - Spectacle
Blue - Madness (Courtesy of Apellosine)

Green and White are somewhat hard to come up with?


Actually, green can have

Mox Aventurine 0
Artifact
Landfall — Whenever a land enters the battlefield under your control, ~ has "T: Add G to your mana pool" until end of turn.

Two more moxes

Copper Mox
Artifact - R
Spectacle - 0 (You may cast this spell for its spectacle cost rather than its mana cost if an opponent lost life this turn.)
T: Add R to your mana pool

Mox Lapis 0
Artifact - R
3, T: Add 1 mana of any color to your mana pool. This ability costs 1 less to activate for each opponent.

one more idea:

Mox Vivianite 0
Artifact R
Morbid - T: add B to your mana pool. Activate this ability only if a creature died this turn.

Assuming Faithless isn't banned - is there an activation cost you think would be "safe" in modern? I mean at this point, even with faithless, a 2 card combo (faithless + 2 land cards in your hand + Bridgmanite + fetch ) for an extra mana isn't bad. What is more since you're discarding land cards you are losing on future land drops. While that matter less as the game goes on - it matters a lot in the early turns, the turns when you want an active mox.

For Bridgmanite, in larget formats, without discard it means it only activates turn 3 which is safe. With discard - the 3 land requirement is severe enough that combo won't be able to run it since they do not have enough lands.

two ideas based off Horizons

Mox Vanadium 0
Artifact R
3, T: Add one mana of any color to your mana pool. This ability costs 1 less to activate for each creature type among creatures you control.

Mox Bridgmanite 0
Artifact R
3, T: Add one mana of any color to your mana pool. This ability costs 1 less to activate for each land card in your graveyard.

Ashes of the Fallen + Dregscape Sliver seems like a fun combo as well

Abuse this with Kaya or Venser - or Just fling Bolases at them?

It does chain into more slivers as cascade lets you cast the cascade spell . . . so if you cascade into a sliver, you cascade again

Doesn't seem that it overwrites their keywords, cards that do usually say "lose all abilities" or something like that?

Oketra, next turn, 2 creatures + 1 Goblin Bushwhacker, attack for 25+?

Best case scenario is:

Turn 1 - Land + Accel
Turn 2 - Land + Accel + Draw
Turn 3 - Land + Oketra
Turn 4 - Creature (1CMC) + Creature (1-2 CMC) + Goblin Bushwhacker

In legacy you can do this:

Turn 1 - Land (+ ManaDork)
Turn 2 - Land - Neoform (if mana dork you can use Eldritch Evolution instead) + Vinedryad / Skyshroud Cutter --> Goblin Dark-Dwellers --> Neoform --> Sire of Insanity (if Evolution just skip right to Sire) + (you have room, I think to run Daze/FOW)

So a pretty consistent, turn 2 way to get a 7/5 and hellbent everyone.

Casting Become Immense using delve, making this a 7/9 and then attacking and casting Become Immense from the grave since his power is now 7 for free turning him into a 13/15 is a fun cheap combo.

I think there was a misunderstanding in this post - I'm not trying to have my keyword become evergreen or replace the wording of future impulse type cards. My ask was essentially whether this could be a 5 color mechanic in a single set. (I was mostly thinking of have [Name] 2 to 3 replace cantrips in a hypothetical set. )
