Functionally, all Standard Duelists are identical with their Deck being chosen randomly each time they spawn in Duel World. After defeating a Standard Duelist a timed delay will start before a replacement can spawn, the player can choose to skip the wait by using either 10 Duel Orbs or 1 Boosted Duel Orb. The AI intelligence of the Standard Duelists starts similar to that of the Level 10 Legendary Duelists to help new players adjust but becomes more intelligent as the player progresses.
This summary is currently incomplete.
A Standard Duelist's Deck is randomly chosen upon spawning, using one of several possible Decks for Standard Duelists. The pool of Decks used by Standard Duelists depends on the player's Stage in Duel World (DM), even for Standard Duelists in Duel World (GX). Once the player reaches a Stage whose number corresponds to a new set of Decks of a particular level, the Standard Duelists start using Decks of that level.
