Unlike every other duelist in Yu-Gi-Oh! Duel Monsters 1, Tristan's card pool contains only three unique cards: Dark Plant, Kuriboh, and Skull Servant. Since decks in Duel Monsters 1 are randomly generated from each character's available card pool, the original Tristan deck was composed entirely of repeated copies of these three monsters.
For this recreation, that limitation proved too restrictive for meaningful gameplay. To preserve the spirit of the original while creating a functional deck, similarly weak monsters from Duel Monsters 1 were added to expand the card pool. Once those options were exhausted, defensive stall cards were included—carefully chosen to prolong the duel without giving the deck a legitimate win condition. The result remains faithful to Tristan's original design philosophy: a deck that survives as long as possible while remaining the weakest.
The DM1 Tristan deck is the weakest deck in the format. It lacks reliable offense, powerful monsters, and meaningful win conditions, forcing it into an almost entirely defensive playstyle. Rather than attempting to defeat the opponent through combat, the deck seeks to prolong the duel by setting monsters in Defense Position, preserving Life Points, and exhausting the opponent's deck.
Against nearly every other deck in the format, this strategy is ineffective, leaving Tristan with virtually no realistic path to victory.
The lone exception is the mirror match. There, Dark Plant becomes the defining card. Since neither player can generate enough offensive pressure to overcome Dark Plant's defense, games frequently end by deck-out. With both players using odentical resources, the outcome is often determined by who takes the first turn, making the matchup largely dependent on the opening die roll.
