Lyman Banner's Decks

Lyman Banner plays an Alchemy Deck which focus on the theme of science and universe.

Anime
As Amnael, Banner plays an Alchemy Deck, which draws a relationship between the science and universe. His strategy relies on the removal of his own cards from the game, supported by the Special Summoning of "Alchemy Beasts", based off common base metals and animals used in alchemy to transmute and refine gold, and the Alchemic Processes, based off four of the seven main stages in transmutation, falling under calcination, dissolution, separation, conjunction, fermentation, distillation and coagulation. In the Japanese version, the positions of the 2 words making up each Alchemic Beast's name are inversed, as well as "the" being omitted entirely. (Their names, as well as the names of the Alchemic Processes, are not hyphenated).

Duel Academy
Lyman Banner runs a Deck focused on Fusion Summoning. This keeps in his theme of alchemy, as he says each time he Fusion Summons, "Alchemy teaches to combine elements into new and richer creations." (2 cards in Fusion Deck unconfirmed.)

Tag Force
In Yu-Gi-Oh! GX Tag Force, Banner uses two Decks, the first of which is called Source-less Existence and focuses on the "Jar" monsters and the Summoning of Token Monsters. He also includes cards that require players to pay Life Points to perform various actions, such as "Toll", "Chain Energy" and "Magical Thorn". He uses two more Decks as Amnael.

Banner's second Deck is called Finite Entity. This Deck still contains some of the "Jar" monsters and action-restricting Spells and Traps, but does not include the same focus on Token Monsters, instead utilizing many Trap Cards that can negate attacks and effects.

As Amnael, he uses two Decks, both of which focus on powering up his monsters by removing cards from play. The Decks utilize cards from the "Different Dimension" archetype in place of the anime-only "Alchemy Beasts", though "Alchemic Kettle - Chaos Distill" and the "Helios" series are included.
