Arakni, Trap-Door

Arakni, Trap-Door has a triggered-static ability that triggers when you become it. When the triggered effect resolves, you may search your deck for a card, banish it face-down, then shuffle. As this is an optional effect, you must be able to resolve the search, banish and shuffle successfully.

If your hero has already become Arakni, Trap-Door (e.g. Arakni hero ability), and another effect would cause you to become Arakni, Trap-Door (e.g. Mask of Deceit), the ability does not trigger.

If you choose to search your deck and it is not empty, you must search for a card and banish it face-down. You cannot choose to fail the search since the effect does not specify any properties of the card to be chosen from the search.

If there are no cards in your deck zone when instructed to shuffle, the zone is still considered shuffled.

Shiyana can trigger this ability if they become Arakni, Trap-Door. Nice Shiyana Card.

Arakni’s second ability triggers at the beginning of your end phase. When this triggered effect resolves, you revert to your base hero. There is no priority for any players during the end phase of a turn.
