One-time effect

The one-time effect icon, also used for Spellburst and Frenzy

One-time effects are triggered effects that activate in response to specific events. However, unlike triggered effects, one-time effects can only activate once.

Notes[edit | edit source]

Secrets, Spellburst, and Frenzy are types of one-time effects that only trigger once after a specific event happens.
When a one-time effect is triggered, the ability is essentially removed from the card. For different types of cards, this means the following:
- For minions (or weapons), e.g. Blademaster Okani, the sparkle that appears under the card's portrait representing the one-time effect disappears after triggering, and the effect can no longer be activated (unless the minion is removed from the battlefield and re-enters it).
- For spells e.g. Secrets, after the one-time effect has been activated, the spell is removed from play.
A card can have multiple one-time effects active at a time, such as by doubling Blademaster Okani's battlecry and choosing both options. In such case, once one of the one-time effects is activated, it will be removed. Once all one-time effects have been activated, the card will no longer have any left.
Similarly to triggered effects, one-time effects are tied to the card. If the card is removed from play, the one-time effect can no longer trigger.
