That sounds really insular and I think it distracts from our other goals with the set.

Creature
Erupt —~ deals 2 damage to target creature. (You may cast this card for its erupt cost from your hand or from the battlefield. If you do, it's an instant spell with the given text.)
2/1

Permanents that are spells.



Instant
Draw two cards, then discard a card.
Acolyte (If you cast this spell for its acolyte cost, it's a 1/1 Spellshaper creature spell with ", Discard a card: You may cast a copy of this card for its mana cost.")

Spells that are creatures that make more spells.

Erupt is really cool.

Can someone write an acceptable reminder text for erupt? I fear that it might eat a lot of space.

I had written quite a bunch until I realized that you could erupt from the battlefield and sorry but that is way too complex for a mechanic at common that already mucks with the rules enough as it is. Make it a sorcery and I could possibly be okay with it, even if I personally prefer Essentia.

What if we made a "keyword" out of 'affect'

I was thinking about this last night. Take Glacinorak for an example.
"...Those permanents can't untap until your next turn."

I kinda want to make some ground with can't (even though it's not exactly a mechanic).
But if I'm going to do that, I want to make sure there is some ways to get around it and the following spell came to mind:

Immunize --
Instant (U)

Target creature is unaffected by other spells, abilities and effects this turn.

--xx--

The example I can think of is that it's supposed to 'undo' Giant Growth. On top of that would allow a creature that can't untap, to untap.
But it also opens up an entire can of worms with definitions being the least of them.

We need a mechanic or gimmick that shows the split of the plane.

Both Mown and Shazzeh have expressed concerns about my bringer mechanic, which makes me nervous because I consider them to be two of the greatest designers on these boards.

Does anyone have any suggestions for bringer to fix the issues they bring up?

As I had said in-thread, I can actually imagine the ability to not be keyworded, and just appear on a single cycle of cards that each bring the archetypal card type of their color.

Or like Hideaway.

I actually like having a cycle of these.

Well, I also generally hold irrational standards towards keywords and get spiteful against anyone who does favorably against me so take it with a grain of salt.
But I'm getting massive cascade vibes from it, except this one doesn't need you to butcher your deck to abuse Hypergenesis, and feels very niche in a deck not made for it.

Barring the easily-fixed problems with spells-with-no-costs-at-all like Hypergenesis, I view this is just a variant on something we already know all too well - Quirion Sentinel, Akki Rockspeaker, and Burning-Tree Emissary didn't break the game and they effectively did much the same as this with less limitation. I mean, this doesn't actually fetch a card out of your deck or anything, it just lets you cast something that is already low-cost for free - which is usually on par with providing an equivalent mana reduction or simply granting the mana with a spending restriction. In fact, it's not even that good, because those help reduce higher-cost things as well.


If Sparkcatcher was reworded to something along the lines of the following, it would do much the same as it was designed to, would be fixed from the easy-color-splashing issue, and would clearly just be an Akki Rockspeaker variant (trading off a spending restriction on the mana for flying on the creature)

Instant bringer (When this permanent enters the battlefield, add to your mana pool. Use this mana only to cast an Instant spell.)

Instant bringer (When this permanent enters the battlefield, the next Instant spell you cast this turn has its cost reduced by .)

Deserts and barren counters.

Desert Nomads –
Creature – Human Nomad
Desertwalk
Prevent all damage that would be dealt to Desert Nomads by Deserts.
2/2

Sand Serpent –
Creature – Serpent (U)
Sand Serpent can't attack unless defending player controls a Desert.
: Put a barren counter on target land. As long as it has a barren counter on it, it's a Desert with ": Add to your mana pool."
Whenever Sand Serpent attacks, remove all barren counters from lands defending player controls.
When the sand runs out, it brings more with it.
6/6

Salt the Earth –
Enchantment – Aura (C)
Enchant land
Enchanted land is a Desert with ": Add to your mana pool."

Sand Spewer –
Artifact Creature – Construct (C)
Sand Spewer's power is equal to the number of Deserts you control.
*/1

Desert Shambler –
Artifact Creature – Juggernaut (R)
Lands you control are Deserts with ": Add to your mana pool."
6/7

Sand Power –
Enchantment (R)
Deserts you control have ": Add to your mana pool."

Sandspreader –
Creature – Horror (U)
Intimidate
Whenever Sandspreader attacks, put a barren counter on target land. As long as it has a barren counter on it, it's a Desert with ": Add to your mana pool."
2/1

Et cetera.

Your counters need to grant the damage ability or they aren't real deserts, also nomads is immune to damage from deserts.

See, this is what we should be talking about. Do we want to make all the cards that turn lands into Deserts give them that clunky ability, or do we just want to update the rules so that all Deserts have ": Add to your mana pool." and make Desert itself a special Desert?

Well if you just want a colorless thing, call them something else. Deserts have a damage ability because they are harsh to cross and it's flavorful.

I'd say Wasteland but that's already taken. I really want them to be Deserts.

Ok, I'll add the damage ability. That makes turning your opponent's lands into Deserts more of a choice anyway, and turning your lands into Deserts more interesting.

If we do deserts, we should do an icicle reprint.
I nominate Dark Depths

No, but what about Tendo Ice Bridge? We can claim that Tendo is a style of bridge, not a place,

Desolate is an appropriate name.
Although I'm not sure if we should try to add subtype support as well. Trying to accomodate for the already high number of types is likely difficult enough as it is.
