Frequently Asked Questions

Low mage serving High Mage Martis at the Desert Shrine. Required before Martis. The default field is Wasteland, which powers up Dinosaur, Rock, and Zombie types.

Difficulty: Very easy.

Threat Cards

  • Labyrinth Wall (3000 DEF, 3500 on Wasteland)

Strategy

Extremely easy. He plays many Uranus cards, so play your THTD in Moon. Rock and Zombie types are powered up by Wasteland, so Mystical Sand and Stone D. can help if you cannot make a THTD yet. If he plays Labyrinth Wall (3500 DEF on Wasteland), use Umi, Mountain, or Raigeki to get past it.

Notable Drops

RankCards
S/A-POWSword Arm of Dragon, Crawling Dragon #2, Dragon Zombie, Wicked Dragon with the Ersatz Head, Oscillo Hero #2, Electric Snake, Mountain

Farming

When defeated on S/A-POW rank, he can drop Mountain field card and some decent Dragons/Thunders. Not a primary farm target but a solid campaign fight.

High Mage Martis

The AI Behavior section displays the duelist's artificial intelligence parameters including Hand Size, Max Fusion Length, Spell Probability, Attack Probability, Low LP Threshold, Critical Deck Size, and the probability distribution for decision states under both Total Domination and Lacks Domination conditions. These values determine how aggressively or defensively the duelist plays during a match.

Some duelists have the Millennium Eye ability (Heishin, Pegasus, Heishin 2nd, Seto 3rd, DarkNite, Nitemare), allowing them to see your face-down cards. The field section shows the terrain bonus that affects certain monster types.

The swords icon next to the duelist's portrait starts a practice duel against this opponent. You can test strategies, practice farming techniques, or challenge yourself against any duelist in the game. The duel uses the duelist's actual deck, AI behavior, and field terrain.

The Deck & Drops section uses tabs to switch between viewing the duelist's Deck and their three drop pools: S,A POW, S,A TEC, and B,C,D POW/TEC. Each tab shows cards with their drop weight (out of 2048) and probability percentage.

Use the search bar to find specific cards by name, ID, type, or stats. Filter by guardian stars, card type (Monster, Magic, Equip, Trap, Ritual), or any custom group using the 'Filter by group' button.

The Simulate Drop tool lets you simulate winning a duel and seeing which cards you would receive. Select a rank (S,A POW, S,A TEC, or B,C,D), choose a quantity (1, 5, 15, or 30 drops), and click the Randomize button. Each drop is drawn from the duelist's weighted card pool, with higher-weight cards appearing more frequently.

The dropdown quantity selector multiplies the number of cards you receive from a single win — drop modes x5, x15, and x30 drastically reduce farming time compared to x1 drops.

The Turn 1 Play table shows the probability of each card the duelist can play on the first turn of a duel. The data is based on ~2 billion simulated duels per duelist, run by GMS and organized by Syura. This is not official game data but should be extremely accurate.

The bold 'This or Lower' column is the most useful metric — it shows the combined chance of the duelist starting with this card's stat or any lower stat. For example, if Kaiba has a 27% 'This or Lower' for 2000 ATK, that means there's a 27% chance he starts with 2000 ATK or less. This helps you understand how rare a particular start is.

The 'This Card %' column shows the individual probability for that specific card. The 'Same Stat %' column shows the combined chance for all cards with the same max stat. The '1 in X' column shows the rarity as '1 in X duels'.

Click column headers to sort the table. Data is not available for Duel Master K since he uses a copy of your own deck.

The Simulate Turn 1 tool randomly draws cards from the duelist's turn 1 distribution. Each card's probability of being drawn matches its 'This Card %' from the table above. Select a quantity (1, 5, 15, or 30 draws) and click the Randomize button to simulate that many starting hands.

This helps you understand what cards you're most likely to face on turn 1 when dueling this opponent. High-stat cards with larger percentages will appear more often in your simulations.
