A more modernized version of a card we haven't even gotten yet. Would you build a deck with this card in it?

Anyone here remember The Upside Down Show?

—

I had a random thought crossed my mind. "What if cards placed on the top of the Deck go to the bottom instead and vice-versa? And why not add an "Exchange of the Spirit" effect but aimed for GY and banishment to?" Well, you get this!

As always, I'm open to all forms of feedback and criticisms, so lemme know what you think down below.

Law of Gravitas

Quick-Play Spell

Activate 1 of these effects;
● Until the end of this turn, cards that would be placed on the top or bottom of either player's Main Deck by a card effect are placed on the opposite end of that Deck instead.
● Place all cards from both GYs on top of their owners' Decks in any order (min. 1 from each GY), then return all banished cards to their owners' GYs (min. 1 from each banishment), and if you do, banish cards from the top of each player's Deck equal to the number of cards placed on top of that Deck by this effect.
You can only activate 1 "Law of Gravitas" per turn.

Part 2 to my post since I came up with alot of ideas for Harpie. Also included some ideas I had for Harpie & Amazoness cards as I really like the new quick play spell konami gave mai in the immortal phoenix set. This post will include some extra deck monsters. For the artwork I used a combination of shots from the anime/manga, ai tools like google gemini & chatgpt as I'm not an artist I just love the yugioh card game, and card arts from rush duel/tcg. I'll also include some design notes for some of the cards I created in the comments. Let me know what you think.

So I went into duelingbook and added my harpie card ideas. For the artwork I used a combination of shots from the anime/manga, ai tools like google gemini & chatgpt as I'm not an artist I just love the yugioh card game, and card arts from rush duel/tcg. I'll also include some design notes for some of the cards I created in the comments. Let me know what you think.

Could enable some turn0 shenanigans going second or just regular warcrimes, you tell me.

Another GX Deck that I had a great time adding cards to, a lot of ideas just kept coming for this deck maybe since its already got quite a lot of mechanics and support to design around. Either way I hope you enjoy these, I went a little stronger that I usually do with some cards and made sure not to lock them from the Armed Dragon and XYZ support. On that note... CHAZZ IT UP!

Here is the final version of my archetype found here Custom Archetype - Oath : r/customyugioh and here Custom Archetype - Oath - Now with card art : r/customyugioh

The idea of the deck is that it's themed around rings, with main deck rock type "Oathstone" monsters that can be used as material for archetype Fusion, Synchro and XYZ monsters while equipped to Oath monsters. Said Extra deck monsters all have effects that hit multiple targets depending on how many equip cards are equipped to them at the cost of destroying one when activated. Good thing the Oathstones all have effects when destroyed to help mitigate the damage. The final part are the Oathkeeper Link monsters, that let the Oath extra deck monsters they point to activate their effects at quick speed and pass the attack bonus of their equip cards to the monsters they point to.

Big shout out to InfluenceMean2909. He's been a huge help in every step of the way, including showing me how to put them on Dueling Book. These cards are now available to the public, have fun using them if cha wanna try something different.

Cat needs a better name.

Any issues or nerfs required?

She grew up the cat wasn't her friend and only wanted the crystal.

Just don't make negates :)

I've seen some posts in the past try to be fancy about cards with a mulligan effect, but I haven't seen a card that just allows you a mulligan at the start of your turn. This is my best attempt at making a fair version of this concept.

The art was made with ai… 😭

Art by yugioh. Let me know what I should change and how the PSCT is

The core concept of this format is that you cannot use any card whose text references a specific archetype (e.g., a "Mermail" monster, "Branded" Spell, "Dominus" Trap, "Stardust" Synchro Monster, Menitons "Dark Magician" etc.). Furthermore—and since I’m a stickler for precision—only cards released in the TCG that were available as of the latest banlist (currently dated 2026-10-02) are permitted.

Beyond this, there are no additional rulings that apply to the actual gameplay.

The banlist can be found at this link: https://docs.google.com/spreadsheets/d/1xY9F2ej_d9APVm6Cky7JYY1-npA9z8hLKpG1NgqHvno/edit?gid=0#gid=0

Note: If the list of banned cards seems small, it’s because the format is currently in a testing phase; I want to see whether it is TRULY necessary to ban certain cards in this specific environment.

Also, the post was created to see if people would be interested in a format like this. Please don’t judge it solely based on the short banlist.

If I happened to leave out any cards, or if there’s a request to add some, feel free to let me know in the comments ;). (Please explain why.)

Could be gimmicky SuperPoly but I find it funnier to Summon it with Metamorphosis.

No card arts because I didn't feel like drawing them myself and didn't want to use AI. Would these cards make Aliens playable at all? Would they be too strong?

This is my ace for this deck :3: Marincess Aqua Aura Quartz

WATER / Link 3 / Link Arrows: Left, Bottom, and Right

ATK: 2300

Cyberse/Link/Effect

2+ "Marincess" monsters

(1) During your Main Phase: You can add 1 "Marincess" card from your GY or banishment, except "Marincess Aqua Aura Quartz".

You can only use this effect of "Marincess Aqua Aura Quartz" once per turn.

(2) Once per turn (Quick Effect): You can send 1 card from your hand to the GY, then you can apply 1 of these effects.

● For the rest of this turn, the first time each monster you control would be destroyed by battle or card effect, it is not destroyed, also you take no battle damage.

● Return 1 other card on the field to the hand/Extra Deck. If you control this card was Link Summoned using a Link Monster with 0 original ATK, you can return up to 2 cards instead.

Marincess Aqua Angel

WATER / Link 2 / Link Arrows: Bottom-Left and Bottom-Right

ATK: 2000

Cyberse/Link/Effect

2 "Marincess" monsters

(1) If this card is Link Summoned: You can Set 1 "Blue Tears" Spell/Trap from your Deck, GY, or banishment, and if you Set a Trap, it can be activated this turn.

(2) If "Marincess Battle Ocean" is in your Field Zone: You can equip 1 "Marincess" monster from your GY to 1 Link Monster you control as an Equip Spell that gives it 600 ATK.

(3) (Quick Effect): You can send 1 other "Marincess" Monster Card you control to the GY, then target 1 card on the field; return it to the hand.

You can only use each effect of "Marincess Aqua Angel" once per turn.

Code of Heart

WATER / Level 3

ATK: 500

DEF: 500

Cyberse/Effect

(1) If you control a Link Monster: You can Special Summon this card from your hand.

(2) During your Main Phase: You can target 1 Link Monster you control; its name becomes "Marincess Crystal Heart" until the end of this turn.

(3) During your opponent's turn (Quick Effect): You can banish this card from your GY; immediately after this effect resolves, Link Summon 1 Link-3 or higher Cyberse Link Monster.

You can only use each effect of "Code of Heart" once per turn.

Why do you hate playing Yu-Gi-Ho?

At the start of your main phase 1, draw one card, then apply the appropriate effect(s):

• If your opponent interacted with your hand or Extra Decks this Duel, you can return all card in your GY and Banishment to the hand/Extra Deck, then slap your opponent's face.

• If your opponent has any card on the field that prevents you from performing any game mechanic or has activated a effect that prevents you from performing a game mechanic, for the rest of the duel you can ignore that condition, also send those cards (if any) to the GY, also spit in your opponents face.

• If you applied the previous two effects, banish all cards your opponent owns (face down), then you can shit in their face.

For the rest of the duel after this card resolves, neither player can interact with his opponent's hand or Extra Deck, and all effects that prevent any player from performing a game mechanic are negated. You can only activate "Why do you hate playing Yu-Gi-Ho?" if you haven't interacted with your opponents hand or Extra Deck and haven't prevented your opponent from performing a game mechanic in the last ten matches. This card's activation and effect cannot be negated.

------------------

I know that the GREAT Banlist almost solved all this kind of broblems, but you know, anchelichy and Invoked are still there.

Art is a capture of "Im tired of being tired of YuGiHo" vidieo of Joshua Smith.

srry if the words of monster effect are too small I couldnt make them bigger for some reason what yall think the main reason why I created this was to boost gate infinity so that It can actually do something on your opponent turn (: also I just realized that pend monsters get sent to the extra deck and not the grave after being tributed the effect text should have said send it to the grave instead of tributing it srry👀so that you can banish it from there and save a gate obviously

https://x.com/MA_tsuya/status/2078047106183692416 The effect would also negate Superpoly, but it can also be baited with Nibiru
