The set we’ll be going with is KonoSuba, because of this one card:

This gives one of your characters +50 soul. The reason we’re going with KonoSuba’s rendition of +50 soul instead of, say, Lucky Star is for one reason: we can use multiple copies of this event in one turn, on one character. And that character is…

The reason we’re using this Goddess card instead of Aqua is for two reasons. The first and probably the most important reason is that this card can restand, so any soul from the first attack will carry over. Second, Aqua has an ability that makes your opponent unable to play backups, but since we want as much soul as we possibly can, we want the opponent to play backups, for reasons I will get into later.

You probably saw this coming. We want to play this climax, then trigger the climax on the first attack, and trigger another on the second attack. If this didn’t already seem unlikely enough to pull off, just you wait.

After playing all four God Blows, next we want to use this brainstormer. We want the brainstormer to reveal 4 climaxes, and have them be the last 4 cards of our deck. So, we refresh our deck and then draw back the four God Blows. Then, of course, we play all four again.

That’s all for our side, and it adds up to a whopping 408 soul! Now you might be thinking, “What about direct attacking to gain 1 more soul?” But we don’t want to direct attack, we want to frontal attack, and the reason for that is we want our opponent to play a very specific card…

[Counter] Send this to Memory. Choose 1 of your Opponent’s Characters in Battle, and that Character gains +X Soul for the turn. X = 4 times # of “Kotori-san’s Rain Doll” in your Memory.

And this is that card. If the opponent is playing iDOLM@STER, they can use this counter on our turn. And not just once, but four times! However, they only need to play it two times on this one turn, targeting our restander twice, and two times in previous turns. This adds another +28 soul to the attack!

So, the final total is 436 soul!

“Could this total be increased if we were playing Standard instead of Neo-Standard?”

The answer to this is YES! If the opponent is playing both the iDOLM@STER counter and this card from KonoSuba:

Thanks to Chikokuman on Reddit for pointing out this card!

Then we can add another +12 soul for a total of 448 soul!

Unfortunately, God Blow requires you to choose a Goddess character. Otherwise, we could choose a card such as Miyuki, Completionist General from Lucky Star who gains +50 soul herself. If, for the sake of argument, we could target Miyuki, then the total would go up to 448-12-6-2-2+51=477, since Miyuki doesn’t restand, so we can only trigger once, and the opponent can only play one counter on Miyuki.

Edit: There are some cards that can give Miyuki the Goddess trait! Thanks to Zaelar on reddit and Lee Guan Da on facebook for pointing these cards out!

If we further extended this to include banned cards and again ignored traits, then we could also make use of Junyou, 2nd Hiyou-class Light Aircraft Carrier who gives all Fleet Girls +1 soul. So, with 4 of these on the field and Miyuki, we get up to 481 soul. But, like I said, we’re ignoring traits and banlist.

Did I miss a card that could increase this total? Let us know in the comment section or send us a message through the contact page.

Thanks for reading!

Edit for Standard:

[S] BRAINSTORM [(1)] Flip over the top 4 cards of your Library and put them in your Waiting Room. For each Climax card revealed this way, choose 1 of your Characters, and that Character gains +1 Soul for the turn.

Thanks to Jeffrey Thompson on Weiss Schwarz Global Community for pointing out this card!

With this card, you can conceivably keep brainstorming climaxes and give your character a ton of soul as long as you have the stock to pay for it. Disgaea also has a climax which lets you choose a character and give it +3 soul, instead of our +2 soul climax.

Edit 2: We received a reply from Opaco with some very good points! I will post it here so others can read it:

Some things you missed in the maximun soul article for Standard: Regarding your opponent, with four “Kaga-class Aircraft Carrier, Kaga”(KC/S25-E036) third ability and 12 stock gives an additional +16 soul. Appart from Kotori-san’s Rain Doll counter, you can attack before with other characters and also use counters like “Manner Lecture”(CGS/WS01-T20) that will increase the soul of characters other than the attacking one, and using restanders can add multiple uses of these. Regarding restanders, while Miyuki itself is not one, once we start using trait change events is possible to make her one for more triggers, counters and Succubus activations, for example by making her <> and using “Energy Drink”(IMC/W41-035), or also events like “Hatsune Miku no Gekishou”(PD/S29-048) and “Shadow of the Labyrinth”( PQ/SE21-07) so you can generate multiple additional attacks with the whole field. And last, once we assume out opponent is cooperating with us, it is possible to just create looping scenarios and go infinte. For example having a small deck/waiting room, use “Rock-Paper-Scissors”(NGL/S58-017) to draw 4 cards with at least another copy of it, a God Blow for Soul, a Freerefresh event and whatever other card (let’s say a plus attack event and we also go infinite power). Give Soul/Power, put the cards back in deck to avoid refresh damage (having a second refresh event on Waiting Room), play the second Rock-Paper-Scissor to draw again the same cards, rinse and repeat ad nauseam.
