Is it possible to have an Aura that's also a land?

Question

As part of asking this question, I tried to prove the first of the two scenarios was possible by inventing a combination of cards that could turn a land into an Aura. To my surprise, I was unable to do so.

This convoluted scenario was the closest I could come:

You control a Havengul Lich. Activate its ability twice and cast Dominating Licid and The Reality Chip from your graveyard. Now cast, in the following order:

1. Mycosynth Lattice (everything is an artifact)
2. Bludgeon Brawl (everything is an Equipment)
3. March of the Machines (everything is a creature)
4. Ashaya, Soul of the Wild (everything is a Forest land)

Then activate the ability Havengul Lich gained from Dominating Licid to turn it into an Aura and attach it to a creature. Per rule 702.151b:

Attaching an Equipment with reconfigure to another creature causes the Equipment to stop being a creature until it becomes unattached from that creature.

But this almost certainly doesn't work, because either the continuous effects still apply and turn Havengul Lich into a creature (which will cause it to be unattached and put into its owner's graveyard), or the reconfigure rule will overwrite Ashaya's effect so that it isn't a land.

Anyway, is there a different combination of cards that can create an Aura land?

Answer 1

Yes it is!

Thanks to @murgatroid99 for mentioning Cloudform in a now-deleted answer.

I control Vedalken Orrery. I cast a Cloudform and it resolves. With its ETB ability on the stack, I first cast Song of the Dryads targeting it and allow Song to resolve, holding priority. Then I cast Enchanted Evening and let it resolve. The result is that Cloudform is an "Enchantment Land — Forest". Then its ETB ability resolves, and it becomes an "Enchantment Land — Forest Aura". We manifest the top card of our library and attach Cloudform to it.

Answer 2

You can make an Aura Land very briefly (it's about as stable as Moscovium).

Have the following cards on the battlefield:

• Mycosynth Lattice
• March of the Machines
• Ashaya, Soul of the Wild

Then cast any aura. It will be an Enchantment Artifact Creature Land - Aura. It will then be put in the graveyard the next time state-based actions are checked because creature's can't be attached to other objects and auras must be attached to some other object (unless it's an aura you cast with "bestow", in which case it will stop being an aura).

Another method:

Start with Invasion of Zendikar and defeat it to obtain Awakened Skyclave, which has "As long as Awakened Skyclave is on the battlefield, it’s a land in addition to its other types."

Use Agatha's Soul Cauldron to give it the activated ability of Gliding Licid (or another of that cycle), which is "{U}, {T}: [This permanent] loses this ability and becomes an Aura enchantment with enchant creature. Attach it to target creature. You may pay {U} to end this effect.".

Activate that ability. It becomes an Aura enchantment, which does override its previous card types – but then it gets attached to a creature, which gives it a new timestamp, and now its ability adds 'land' to its card types after they are set to 'enchantment'.
