triggered abilities which are written with the trigger condition in the middle of the ability, rather than at the beginning.
405.1. A static ability does something all the time rather than being activated or triggered. The ability isn’t played-it just “exists.” Such abilities apply only while the ability is on a permanent in play, unless the ability is covered by rule 402.8.
405.2. Some objects have intrinsic static abilities which state that the object “has” one or more characteristic values; “is” one or more particular types, supertypes, subtypes, or colors; or that one or more of its characteristics “is” or “are” a particular value. These abilities are characteristic-setting abilities. Abilities of an object that affect the characteristics of another object are not characteristic-setting abilities; neither are abilities that an object grants to itself. See rule 201, “Characteristics,” and rule 418.5a.
405.2a A characteristic-setting ability that states that an object is one or more particular types, supertypes, subtypes, or colors applies no matter which zone the object it’s on is in. This rule doesn’t apply to other characteristic-setting abilities.
406.1. A mana ability is either
406.2. Spells that put mana into a player’s mana pool aren’t mana abilities. They’re played and resolved exactly like any other spells. Triggered abilities that put mana into a player’s mana pool aren’t mana abilities if they trigger from events other than activating mana abilities. They go on the stack and resolve like any other triggered abilities.
406.3. A mana ability remains a mana ability even if the game state doesn’t allow it to produce mana.
406.4. A mana ability can be activated or triggered. Mana abilities are played and resolved like other abilities, but they don’t go on the stack, so they can’t be countered or responded to. See rule 411, “Playing Mana Abilities,” and rule 408.2, “Actions That Don’t Use the Stack.”
406.5. Abilities (other than mana abilities) that trigger on playing mana abilities do use the stack.
406.6. If a mana ability would produce one or more mana of an undefined type, it produces no mana instead.
407.1. Effects can add or remove abilities of objects. An effect that adds an ability will state that the object “gains” or “has” that ability. An effect that removes an ability will state that the object “loses” that ability. If two or more effects add and remove the same ability, in general the most recent one prevails. (See rule 418.5, “Interaction of Continuous Effects.”)
407.2. An effect that sets an object’s characteristic, or simply states a quality of that object, is different from an ability granted by an effect. When an object “gains” or “has” an ability, that ability can be removed by another effect. If an effect defines a characteristic of the object (“[permanent] is [characteristic value]”), it’s not granting an ability. (See rule 405.2.)
407.3. Effects that remove an ability remove all instances of it.
408.1. Timing, Priority, and the Stack
408.1a Spells and activated abilities can be played only at certain times and follow a set of rules for doing so.
408.1b Spells and activated abilities are played by players (if they choose) using a system of priority, while other types of abilities and effects are automatically generated by the game rules. Each time a player would get
