Gemini Monsters

Gemini monsters are a kind of Monster card in the TCG and HCCG; specifically, they are a subtype of Effect Monsters. They are a relatively newer subtype to the game, and fewer than 10 Gemini monsters currently exist in HCCG. They are color-coded orange.

All Gemini monsters are treated as Normal Monsters when they are first revealed to the opponent, either on the field or in the Graveyard. In order for them to become Effect monsters, they must be Normal Summoned again while face-up on the field; this is colloquially known in HCCG as a "Gemini Summon". Once they are Gemini Summoned, their effects can activate as if they were regular Effect monsters, and they remain Effect monsters for the remainder of the Duel (unless they are returned to the Deck and played again).

The built-in effect of all Gemini monsters is: "This card is treated as a Normal Monster while face-up or in the Graveyard. While this card is a face-up Normal Monster, you can Gemini Summon it to have it become an Effect Monster." In the TCG, the term "Gemini Summon" is not used in card text.

Because Gemini monsters require their controller to use an extra Normal Summon in order for their effects to activate, they are generally considered inferior to other Effect monsters. However, before they are Gemini Summoned, they do gain access to generic Normal monster support cards, and thus many decks using Gemini monsters contain this kind of strategy. Currently, many of the Gemini monsters in HCCG are of the FIRE attribute.
