Playing style
"Snake-Eye" is a theme focused around Level 1 FIRE monsters and Special Summoning monsters from the Spell & Trap Zone treated as Continuous Spell Cards. The bulk of its monster line-up is made of Level 1 FIRE Pyro monsters that feature various consistency effects as well as a shared effect to send themselves and another card the player controls to Special Summon a "Snake-Eye" monster from the hand or Deck, excluding that respective card. The boss of the theme is "Snake-Eyes Flamberge Dragon", a Level 8 FIRE Dragon monster able to place any monster on the field or in either GY on the field as a Continuous Spell Card to its owner's field. On top of this, during the opponent's turn, it is able to take a monster treated as a Continuous Spell and Special Summon it to the field of its controller, leading to passive snatching of the opponent's stronger monsters.
The theme is supported by three Spell Cards and one Trap Card primarily. The original card for the theme, "Sinful Spoils of Subversion - Snake-Eye", is a basic Spell Card able to place a monster on either side of the field to the Spell & Trap Zone as a Continuous Spell. The Field Spell Card, "Divine Temple of the Snake-Eye", places a "Snake-Eye" monster onto the field as a Continuous Spell from hand, Deck, or GY, gives all Level 1 FIRE monsters a sizable stat gain of 1100 ATK, and is able to Special Summon a monster treated as a Continuous Spell to your field once per turn when the opponent Normal or Special Summons a monster. As well, the final Spell Card, "Original Sinful Spoils - Snake-Eye", is able to summon any Level 1 FIRE monster from the hand or Deck and also can banish itself to add any Level 1 FIRE monster from the Deck to the hand at the added cost of placing a "Snake-Eye" or "Diabellstar" monster at the bottom of the deck, cementing a further connection between the two themes. The Trap Card of the theme, "Startling Stare of the Snake-Eyes", does much of the same things the rest of the theme can do such as placing monsters in the backrow and Special Summoning them back, but the user needs to have "Snake-Eye" monsters on the field whose Levels total to 2 or more.
