Yu-Gi-Oh!

Two duelists start with 8000 life points and try to knock the other to zero. That is the whole win condition, plus a couple of exotic alternatives, and it hides one of the most complicated card games ever printed.

Yu-Gi-Oh has no resource cost system. There is no mana, no energy, no land. If a card is in your hand and its conditions are met, you can play it. Instead of paying for cards, you pay with actions: one Normal Summon per turn, cards you had to discard, monsters you had to give up. That single design choice is why modern Yu-Gi-Oh turns are so long and so explosive.

• Fast. Games are often decided in three or four turns at competitive level.
• Interactive in a strange way: most interaction happens on your OPPONENT'S turn, from set traps and from hand traps.
• Enormous card pool, no rotation. A card printed twenty years ago is still legal.
• The video games (Master Duel) and this site's Duel are the cheapest ways in.

Three card types, and everything follows from telling them apart at a glance.

• Monsters (yellow, orange, blue, purple, black, white borders). They have a Level or Rank, an Attribute, a Type, ATK and DEF. They fight.
• Spells (green). Played from your hand in your Main Phase, or set face down for later if they are Quick-Play.
• Traps (magenta). Must be SET face down first and can only be activated from the following turn onward. This delay is the whole reason bluffing exists.

Monsters come in flavours that matter enormously: Normal and Effect monsters live in your main deck, while Fusion, Synchro, Xyz and Link monsters live in your Extra Deck and are summoned by meeting a condition with cards already on your field. Ritual monsters sit in the main deck but need a Ritual Spell.

1. 1

   Draw Phase

   Draw one card. The player going first does not draw on the very first turn of the game.

2. 2

   Standby Phase

   Maintenance effects resolve here. Usually nothing happens.

3. 3

   Main Phase 1

   The phase where the game happens. Normal Summon or Set one monster, Special Summon as many as your cards allow, activate Spells, set Spells and Traps, change monster positions.

4. 4

   Battle Phase

   Declare attacks one monster at a time. Attack monsters or, if the opponent has none, attack directly. Battle damage is the difference in ATK, and attacking into a bigger monster damages YOU.

5. 5

   Main Phase 2

   A second main phase after combat, for anything you held back.

6. 6

   End Phase

   Discard down to six cards in hand. End-of-turn effects resolve. Pass.

Summoning is where the skill lives. You get ONE Normal Summon per turn, and a monster of Level 5 or 6 needs one tribute, Level 7 or higher needs two. Special Summons do not use that one summon, which is why the entire modern game is built on chaining Special Summons together into a board.

• Main deck: 40 to 60 cards. Serious players run 40, because a smaller deck draws its best cards more often.
• Extra deck: up to 15, and it holds only Fusion, Synchro, Xyz and Link monsters.
• Side deck: up to 15, swapped between games in a match to answer what your opponent just did to you.
• Three copies of any card maximum, unless the Forbidden and Limited list restricts it to one, two, or none.

A functional deck is roughly: a core engine (the archetype cards that combo together), a set of starters that begin your combo, extenders that continue it through interruption, hand traps that interrupt the opponent, and a small number of generic removal cards. New players almost always run too many "cool" cards and not enough copies of the card their deck is actually about.

• Advanced is the standard competitive format, governed by the Forbidden and Limited list, which changes several times a year.
• Traditional ignores the ban list and turns Forbidden cards into one-ofs. It is a casual curiosity.
• Speed Duel is a smaller, faster version with its own card pool and 4000 life points.
• Rush Duel is a separate game entirely, popular in Japan, not cross-compatible.
• Master Duel is the digital client most people actually grind, and it uses its own ban list.

There is no rotation. Sets come out constantly, old cards stay legal, and the ban list is the only thing keeping the format from breaking. That means a deck you build stays legal for years, and also that a single announcement can end it.

Yu-Gi-Oh started as a manga about a boy who solves an Egyptian puzzle and gets a spirit in his head who is very good at games. The card game was one arc of it, it ate the entire franchise, and the anime has run in some form for over twenty years.

• The original series (Duel Monsters) gave the game its icons: Dark Magician, Blue-Eyes White Dragon, Exodia, the Egyptian God cards.
• Each later series introduced a summoning mechanic alongside its story: GX and Fusion, 5Ds and Synchro, ZEXAL and Xyz, ARC-V and Pendulum, VRAINS and Link.
• The cards themselves carry a huge amount of self-contained story. Archetypes like Dogmatika, Branded, Tearlaments and Kashtira tell running narratives across dozens of cards, told only in art and flavour text.
• Serious fans read the "lore order" of a set the way you would read a comic. It is genuinely good, and completely optional.

This is the card game the platform actually runs. The whole Yu-Gi-Oh database is ingested into the Duel pool, so packs contain real cards with real art, and the duel engine plays a simplified but genuine match.

1. 1

   Get cards

   Open packs from the card shop in Discord (the card shop channel hub, or the Card shop button inside /duel). Channel point redemptions on stream drop packs too.

2. 2

   Look at what you own

   Your binder lives on the website, and it is shareable. Collections are also browsable at aquilo.gg/game/duel.

3. 3

   Duel someone

   Run /duel challenge and pick an opponent, with an optional Bolts wager that both sides pay in at accept. /duel join enters a private room with a six character code.

4. 4

   Trade

   Duplicates are currency. The trade and market surfaces let you turn spares into cards you actually want.

• The official Konami rulebook is the authority on turn structure and timing, and it is free.
• The Yugipedia wiki for card rulings, archetype lists and the current Forbidden and Limited list.
• Master Duel if you want to practise the modern game for free against real people.
• Ask in our Discord. Someone in there has a deck list and an opinion about it.
