Sleight

Sleight is the term used to refer to certain three-card combinations in Kingdom Hearts: Chain of Memories. They are learned by either Riku or Sora. Sleights may be learned upon level-up, or they may be acquired through story events (as in the case of Trinity Limit). More powerful than single-card attacks, magic, or summons, sleights are often used in boss battles.

Attack Sleights
Attack sleights are formed by combining 3 Attack Cards.

Magic Sleights
Magic sleights are formed from 2-3 Magic Cards.

Riku's Sleights
Riku does not learn sleights upon reaching a certain level. Rather, he has access to four sleights throughout the entire game, unless Dark Mode has not been activated or he does not have access to a King Mickey Friend Card. As a result, MM Miracle is the only sleight Riku can activate outside of Dark Mode.

Re-Chain of Memories
In addition to the above sleights, Riku has a new sleight in Kingdom Hearts: re-Chain of Memories. For this sleight, Riku combines a King Mickey card with 2 Soul Eater cards or 2 King Mickey cards with a single Soul Eater card, which allows him to perform a new combo move with King Mickey, where they spin in a circle and attack all the surrounding enemies.
