Cipher Monster

Cipher Monsters are new monsters used in Yu-Gi-Oh! Illusion. They are Special Summoned by Cipher Summon. They are stored in the Extra Deck and the color of their card frame is dark blue to differ from Ritual and Link Monsters, who are a classic blue.

The Cipher Monsters use a unique method of saying which materials they use; they use a "keyword" instead of a line of which materials they use, and you have to shuffle monsters from your side of the field and Graveyard into the Deck(or banish for Extra Deck monsters) whose category of monster (Ritual, Effect, Fusion, Synchro, etc.) matches one letter of the keyword. Remember that the maximum of materials is 8. Example is that, if there is a card whose "keyword" is FRIEX, you need to shuffle a monster whose category of monster starts with F, then with R, then with I, then with E and then with X. The keyword should have at least 2 letters, with the maximum being 8.

A Cipher-oriented deck is possible to use monsters of different mechanics to produce, in order to have the spectrum of mechanics needed for the Summon.

In case a card is a Pendulum, Shift or Snare monster, but it is part of another mechanic (e.g. Xyz Pendulum, Fusion Shift or Synchro Snare), then you can use that card as any letter of those it belongs. Example, an Xyz Pendulum can be used as either X or P for a keyword of a Cipher Monster.
