Detain

Detain is a keyword action that was introduced in Return to Ravnica as the guild mechanic of the Azorius guild. 
==Description==
Detain means: "Until your next turn, that permanent can't attack or block and its activated abilities can't be activated." In effect, for one round of turns, it is an <c>Arrest</c> or <c>Faith's Fetters</c> for any permanent.
===History===
Dragon's Maze added 2 cards with detain. More then ten years later it was reused on the Assassin's Creed card .
==Rules==
==Rulings==
*Activated abilities include a colon and are written in the form “[cost]: [effect].” No one can activate any activated abilities, including mana abilities, of a detained permanent.
*The static abilities of a detained permanent still apply. The triggered abilities of a detained permanent can still trigger.
*If a creature is already attacking or blocking when it’s detained, it won’t be removed from combat. It will continue to attack or block.
*If a permanent’s activated ability is on the stack when that permanent is detained, the ability will be unaffected.
*If a noncreature permanent is detained and later turns into a creature, it won’t be able to attack or block.
*When a player leaves a multiplayer game, any continuous effects with durations that last until that player's next turn or until a specific point in that turn will last until that turn would have begun. They neither expire immediately nor last indefinitely.
==Trivia==
*While common as a static ability on Auras, four cards have outlined the rules text of Detain as their effect , , , and .
