Changes
not really a glitch, that's always been in the series.
* The computer rarely chains your cards, only using "[[Jar of Greed]]", "[[Magic Jammer]]", "[[Seven Tools of the Bandit]]", "[[Royal Decree]]", and the specific Spell-countering cards like "[[Anti Raigeki|Anti-Raigeki]]" or "[[Call of the Dark]]".
* Sometimes the AI shows signs of "knowing" face-down cards.
* If a card effect would make one of the AI's monsters stronger than your highest-ATK monster, but the monster is naturally weaker than the latter, the AI will still play it in Defense Position. However, it will switch the monster to Attack Position at the next opportunity.
* Terrain bonuses sometimes do not benefit the player, but it does benefits AI.
