Have you put this format through live play?

TypicalTimmy I have no idea right now. Five colors, legendary creatures, enchantments, and all of the fighters are in the 99.

Gvan It was Standard-legal seven years ago, and I assume it hasn't been modified since then. It's technically closer to Block Constructed at this point, but I don't see a problem with it labeled Standard at time of construction.

Second Draw has been added, and I see the SNC keywords and Toxic as checkbox options. Thanks to whoever took care of that.

Welcome to the club, and thanks for the upvote!

I usually try to let at least 3-4 challenges go between my responses, but why not.

Soul Calibur

Legendary Artifact - Equipment

Equipped creature gets +2/+2 and has lifelink and vigilance. As long as equipped creature is white, it gets an additional +3/+3.

Whenever equipped creature deals damage to a creature, if that creature has power 5 or greater, exile that creature.

Whenever a creature with power 4 or greater or a legendary creature enters the battlefield under your control, you may equip Soul Calibur to that creature.

And just for fun,

Inferno of Soul Edge

Legendary Creature - Avatar Nightmare

First strike, wither, ward

When Inferno of Soul Edge enters the battlefield, you may search your library, hand, and graveyard for a card named Soul Edge and put it into the battlefield, then shuffle.

Whenever a creature an opponent controls dies, if it had 0 or less toughness, put it on the battlefield under your control and attach Soul Edge to it.

7/7

Let's keep the video game legendary equipment going.

TypicalTimmy I didn't expect to see that. I'm on-again-off-again designing a Soul Calibur 6-themed EDH deck. This is beautiful. Thank you!

Colossus Hammer is a good starting point.

Rhonas's Exultation

Enchantment - Aura

Enchant creature

Enchanted creature gets +1/+1 for each +1/+1 counter on it and has trample and "Sacrifice this creature: Creatures you control get +1/+1 and gain trample until end of turn."

Create a ridiculously big weapon, like Ogre's Cleaver, Giant's Skewer, or Enormous Energy Blade. If you can, make it even more bigger. (Good grammar, right?)

Argh. I blame Zaffai, Thunder Conductor for that name/text error.

Jelly Bloom

Enchantment

Storm

When an opponent casts their second spell each turn, Jelly Swarm becomes a 3/3 Jellyfish creature with "Whenever this creature deals damage to a creature, tap that creature and put a stun counter on it." until end of turn.

, Sacrifice Jelly Swarm: Target opponent copies target instant or sorcery you control. They may choose new targets for the copy.

Create a Jellyfish creature that fits under a Jeskai color identity. Bonus points if it's non-blue.

TypicalTimmy Could you please provide a source for that?

https://magic.wizards.com/en/story/koth-planeswalker doesn't specifically use the word "geomancer," but it does mention him "burying foes beneath avalanches of stone or incinerating them in rivers of molten lava." That's in line with what Slagstorm shows, which appears to be Koth flying stone through the air, possibly lifting a good chunk of a mountain.

I can't find any source that describes Koth as a transmuter, either using that word or describing him as changing one material into another. I haven't gone through all the short stories or novels, so there might be something there I don't know about, but the summaries don't seem to suggest anything like transmuting. The unofficial site https://mtg.fandom.com/wiki/Koth_of_the_Hammer says that Koth's "specialty is geomancy" with a link to a Doug Beyer article from January 2011 called Mail Bonding, but that article's been removed from the WotC site.

https://magic.wizards.com/en/story/nahiri-planeswalker is less descriptive of her abilities, but your summary matches what I've found. I just don't see Koth being described as you say anywhere, either directly or by inference. He's able to harden or soften, change the shape of, and "purify" or un-corrupt metal and stone, but not change what it's made out of, as far I can tell.

KBgamer Yes, you are. Not sure how I missed that.

Ill Wind

Enchantment

At the beginning of each player's end step, that player returns a permanent they control to its owner's hand, then discards a card.

The breeze would have been refreshing, if it wasn't noxious and freezing.

Create an explosion.

I'm glad to help! I should probably add at this point that I'm not an expert with life gain, so other people may have more in-depth suggestions.

Pre-completion Nahiri, the Lithomancer is described as having special power over stone and metal, often using that to create stone and metal blades.

Koth of the Hammer is a geomancer, manipulating stone and heat as it relates to lava. Thanks to being born on Mirrodin, he's able to use this to purify and heat metal.

It seems like the difference between their respective abilities is mostly semantic. Both of them are shown using rocks, metal, and heat as weapons and armor. About the only differences I see are that Nahiri has manipulated worked stone, while Koth has only used raw stone, and that Koth goes bigger scale with landslides and eruptions while Nahiri mostly focuses on smaller-scale shaping and crafting. This appears to be mostly preference, though, with Nahiri's Lithoforming, Nahiri, Storm of Stone, Smelt, and Darksteel Plate.

Ajani's Welcome would be a very good addition.

I'm less sure of Panharmonicon. At four mana, you want to start moving toward your win condition. Run a few games with one or two and see how often it makes a difference when it comes out--if the game would have played out mostly the same with or without PHicon, if it didn't affect whether you won or lost, then it's not really helping. Panharmonicon is a very good card in the right deck, but this might not be it.

The Thief of Sanity set doesn't really focus the life gain strategy, and the Dimir Guildgates mostly slow down your production. They're fun cards, but I would use them in a different deck. At 65 cards, cutting those eight, one Revenge of Ravens, and replacing the lands with or sources would improve speed and consistency.

Some smaller tweaks would be to drop a second Revenge of Ravens for a fourth Ajani's Pridemate, adding some more removal, and maybe another life gain payoff like Indulging Patrician.

I was around when planeswalkers were introduced, and I remember a lot of comments about how they were unnecessary since existing cards already do everything, they were too complicated and powerful with three free abilities (reanimate everything for five mana? mill twenty for three mana? Overrun every other turn for *two* mana?, nobody's ever going to use them and they were a gimmicky waste of time, and they pulled focus away from the players because players are the real planeswalkers. Some of these arguments still float around, some are being transferred to Battles, and some have faded away as people learned how to use them. In the last few years (don't tell me the real number), the game has adapted, players have adapted, and planeswalkers are now generally expected and uncontroversial.

Has there been any mention of Gimli yet? If not, I'd like to see something that's not Equipment, but I'm having a hard time coming up with anything that's not some kind of Boros (maybe Naya) combat. Most modern fantasy Dwarves (or dwarfs) are small variations of Tolkien's, and Bruenor Battlehammer, from what I know of him, would fit pretty much directly into this world, combining Forgotten Realms, Magic: the Gathering, and Lord of the Rings into one bearded clanking package.
