Of the five, this is the only one that really concerns me. Let me know what you think

I think if we're not doing the Mortuary Mire ability, this needs a restriction of some sort. Other options: ­

­
• Target creature gets -1/-0 and blocks this turn if able. ­
­
• Target creature gets +1/+1 and gains deathtouch. ­
­
• Add to your mana pool. ­
­

The first doesn't seem black. The second is absurd. The third is weird considering the GU one.

Edit: Ignore the first point. I read it as +1/+0 for some reason. Still not a huge fan, but it is black-ish after all.

Crosslinking the rest of the cycle: Filigree Factory, Corrupted Courtroom, Weapons Cache, AEther Plantation.

I'd be fine with an uncommon two-colour Mortuary Mire. I think that's better than any of the other options suggested so far. "Target creature gains deathtouch UEOT" (without the +1/+1) is probably reasonable, and quite interesting.

The third option (ETB add ) I think is pretty cool, but wants to be on a whole cycle all by itself.

Agreed.

I don't think we want to go back and make colorless mana actually important, though the sooner we decide that the better. I do think that ETB add will eventually be a cycle.

The third option as a cycle is the most elegant in my opinion. Your right we don't care about in the way OGW does but having minor reasons to like artifacts more is certainly a good thing now that Advancement is gone.

"Add " doesn't have to mean that colourless mana is important. Unknown Shores and Llanowar Wastes and so on were all sensible cards in their original formats even without Kozilek and friends. "Add " is a very natural thing to put on a land. It doesn't even have anything to do with artifacts: 80%+ of Magic cards include a cost that you can spend on.

A land that ETBTs but adds on ETB is a card that people love to keep designing, and I'm sure it'll get printed eventually now that Crumbling Vestige has introduced the pattern (effectively in reverse).

Sigh, I do see how cool that is, but the intent was for two color spell lands. If we're going to do that effect, I would probably make it the full cycle, not a one off.

CasualR well thats what I'm suggesting. Dual color spell lands seem like both narrow design space, difficult to balance and potentially something more suited to rare.

Fair enough. Full ten or just five?

All 5. Looking at our Archetypes I think the enemy pairs could use the the extra flavor and fixing as they are not quite as strongly themed.
