When [[SEGOC]]''' ({{Ruby|強|きょう}}{{Ruby|制|せい}}{{Ruby|効|こう}}{{Ruby|果|か}} ''Kyōsei Kōka'', and two or more effects trigger at the same time"Forced Effect"), the Compulsory also known as '''compulsory effects all go to the beginning of the Chain''', and the are [[Optional Card effect|effects]] are put to the end of the Chain. Examples of Compulsory Effects are that must [[D.D. Assailantactivate]], if they meet their [[Sanganactivation requirement|activation conditions]]. Mandatory effects lack the phrase "You can" in their card text. (In Japanese, [[Witch of the Black Forest]] and [[Zaborg mandatory effects are indicated by the Thunder Monarch]] and for [[Anime]] only monsters [[Compulsory]] effects [[Guardian Dreadscythe]] is a prime exampletext {{Ruby|発|はつ}}{{Ruby|動|どう}}する ''Hatsudō suru'' "Activate".)
List of Card such as "[[Caius the Shadow Monarch]]" and "[[Man-Eater Bug]]" have powerful effects, but because they are mandatory effects, if they are triggered when the opponent has no monsters, the player must target their own cards:.
* [[Sacred Phoenix of Nephthys]]==Mechanics==* When a mandatory effect meets its activation conditions, it always activates, even if it has no valid [[Sangantarget]]* or it would have no effect. Mandatory effects cannot [[Vampire Lord]]* [[Witch of missing the Black Forest]]* [[Zaborg timing|miss the Thunder Monarchtiming]]* . If a mandatory effect must activate during a particular [[Man-Eater Bugphase]]* or [[Old Vindictive Magician]]* [[Magician of Faith]]* [[Mask of Darkness]]* [[Skelengelstep]], it is not possible to proceed to the next phase or step until that effect is activated.
{{Monsters}}When [[Simultaneous Effects Go On Chain|multiple effects trigger at the same time]], they are all placed on a [[Chain]], with the turn player's mandatory effects being activated first, followed by the non-turn player's mandatory effects. Optional effects can only be activated at higher [[Chain Link]]s.
