2/2

~~~~~

Manifest: Put a card face-down onto the battlefield. It's a 2/2 creature with no types. When a manifested, morphed, or face-down card changes zones, reveal it, to show that you're not cheating.

Manifest made me sad because it's so little used and such an interesting mechanic. Make another card with manifest.

Weatherlight Restored

-4: Weatherlight Restored deals 4 damage to any target.

-6: Choose a card you own. Put that card into your hand.

4

~~~~~

Artifact in parenthesis due to type line constraints. If Karn isn't an artifact, the Weatherlight doesn't need to be.

The Weatherlight has always been more a transport than anything. It gathers items, and that's all it does. It's really good at that though....

Also it has guns.

Make a creature card for one of the Gatewatch for when they lose their spark.

Slimefoot, the Stowaway

Legendary Creature - Fungus

Whenever a Saproling you control dies, each opponent loses 1 life and you gain 1 life.

~~~~~

Aww, I liked old Slimefoot.

Technically ninja'd, but it's fine. I did that challenge.

Fix a card on any banlist so that it doesn't have to be banned anymore.

Venomous Whispers

Instant

Gain control of target creature if it's converted mana cost is less than or equal to the number of poison counters on it.

~~~~~

Venomous is an interesting mechanic. It's incredibly parasitic though: it only works with cards that have venomous, and relies heavily on having those cards.

Someone do something. I'll let the forum decide your fate.

...ninja'd.

Current challenge, from Radarmonkey:

Make a legendary instant/sorcery/enchantment that fits with the current story.

~~~~~

Bolas got his shit wrecked during the Mending. He looked for a bunch of different ways to regain his power after the Mending, and while he eventually decided on the Maelstrom plan in Alara, he probably looked into a few other options. This is a vestige of him he sent out to investigate the suitability of the Chasm for his purposes.

Everyone's enjoying this. Keep going, I'll be lurking.

Exsanguination Therapy

Instant

Remove all poison counters from target player. That player loses 2 life for each counter removed this way.

"Don't worry. This will hurt less than the alternative."

~~~~~

As I got ninja'd, I'll be back once I figure out what's been going on in this thread while I've been gone.

Did you say make an Avatar for each Ravnican guild?

...because that's what I heard.

I'll be back.

Continue as usual. We'll see how fast I can finish these.

Agrus Kos, Restless Veteran

Legendary Creature - Spirit Soldier

He's still kicking.

"See that star? It's gettin' closer, see. When it comes down, I'll have a front-row seat to the biggest explosion in history!"

Make a Vorthos card that matches the mood of Herald of the Crater.

3

~~~~~

A lean, mean, reincarnation machine.

I hate that there's no room on the type line to make Squee a Legendary Tribal Planeswalker - Squee Goblin.

Make an Orzhov planeswalker, but instead of weighted towards black, make it mechanically trend white.

Tiamat, Mother of Dragons

Legendary Creature - Dragon God

Flying, Trample, Indestructable

If Tiamat, Mother of Dragons would be exiled, instead shuffle her into her owner's library.

Mother of all Chromatic Dragons.
