Activation

This is not the same as the "activate" used for P-011.
. Players choose a triggered effect to apply.
== Summary ==
Declaring the use of an effect is called "activating" the effect. You would choose to activate an effect that was triggered last. While effects can trigger at the same time, effects must be activated one at a time. Activating an effect is not the same as "triggering" an effect.
It is possible for a player to select an effect to not activate and this would remove its status as "triggered" or "pending activation". Players can also choose effects that don't meet their activation conditions, in this case effects will fail to activate but the "pending activation" status will still be removed.
 conditions prevent an effect from being activated more than once per turn. If an effect fails to activate, it does not count towards the count.
Note: Official Bandai materials often confuses and swaps the "trigger" and "activate" around, but they are regardless not the same as the Detailed Rules document and emails have pointed out. Please be careful when extrapolating from materials that confuse the two.
== Activation Conditions ==
Activation Conditions are commonly denoted by "if". Activation Conditions are only checked when a player chooses an effect to activate. If an effect the player has chosen meets its activation conditions, the effect is considered to have activated. If it fails to meet its conditions, it is not activated.
Effects that fail to meet their activations do not use up their but are still removed from pending if they were declared by a player. counts and conditions are checked at the same time as activation conditions.
== Failing to Activate ==
After being chosen, a set of conditions are checked to verify whether an effect can succeed in activation. An effect can only fail to activate under the following conditions:
* If the effect belongs to a Digimon or Tamer, and the Digimon/Tamer has left the required area (Trash or Battle Area) or lost the effect.
* The effect is a , , or effect and has already been successfully activated that many times this turn (per card).
* The effect fails to meet its Activation Conditions.
It is important to note, that effects are not used up if the effect fails to activate due to the above conditions. However, if an effect successfully activates the is used up even if the effect has no affect on the game state.
==Activating from the Trash==
Digivolution cards stop being treated as Digivolution cards when they're placed in the trash, but when activating their effects, the effect activates as if they were in the same state they were in when deleted. (Example: A card with the inherited effect ": If this Digimon has [Greymon] in its name" is deleted as one of the digivolution cards in a [Greymon] card. It stops being treated as a digivolution card when it moves to the trash, but is still able to activate its effect as if it were one of [Greymon]'s digivolution cards.) 
If a card with a pending effect moves from the trash to a player's hand/deck/battle area/breeding area, the card is no longer in the trash, so the effect doesn't activate.
Additionally, if the effect belongs to a digivolution card, even if the card with the effect itself remains in the trash, if the Digimon card placed on top of the card at the time of deletion leaves the trash, the card with the effect will no longer be considered to be a digivolution card, so the effect doesn't activate. If the digivolution card leaves the trash, the effect can still be activated as the effect is considered one of the Digimon's effects and not the digivolution card's effect.
(Example: An [Agumon] with an inherited effect is deleted as part of a [Greymon]'s digivolution cards. If the [Greymon] card returns to your hand from the trash while [Agumon]'s inherited effect is pending activation, [Agumon]'s inherited effect will no longer be able to be activated.)
The same applies to other effects triggered in the trash such as 's "when this card is trashed from your deck" effect.
Even though tokens are removed from play instead of sent to the trash, they can still activate effects.
==Once Per Turn Effects==
 effects cannot be activated more than once per turn. are counted Once per Turn per card.
If multiple Digimon have the same all of those Digimon can use it once as they are different cards. If the same Digimon instance is given the same effect by a different card (even if it has the same Card ID), that Digimon can use the effect again because it is a different card. If a effect fails to fulfil its activation conditions even though it's a mandatory effect can still be activated during the turn. If a card moves out of the Digimon Instance it becomes a different card.
#A Digimon uses its own effect and is . It then digivolves back into another of the same card. That effect is from a new card so it can use the again.
#A Digimon uses an inherited effect and is so that it loses the inherited effect. If it digivolves back into a new Digimon. That effect is from the same card so it cannot use the effect again.
#A Digimon uses a effect a series of actions happen so that it is played by as a new Digimon. While the effect is from the same card, it is from a new Digimon so it can use the again.
#A Digimon uses a effect, the card the effect was attached to leaves to another zone. It is then placed back underneath the same Digimon by another effect. It is the same Digimon but a new card so it can use the effect again.
===Examples===
A uses its and then digivolves into another . The can be used because it is depending per card even if it is the same Digimon. It is a different Rafflesimon card so the was not used up for that card.
's inherited effect is activated and the Digimon on top is hit by a that causes it to become again and lose its inherited effect. If you digivolve that into another Digimon the cannot be used, because even though it lost and re-gained the effect. is dependent on card, and because it's the same card the was already used.
's inherited effect is activated and then the same card is played by the effect of . It digivolves into another Digimon. If a source is trashed its can still be used because even though it is the same card because it was played as a separate Digimon.
 is activated, it is then by a card effect. The effect of is then used to place the same Strabimon card underneath the same Digimon. It is allowed to use the same effect it was placed underneath the same Digimon as a new card.
