Know When to Hold 'em's "card lock" effect visually displays runes which countdown the effect's remaining turns. The lock only applies to the drawn card, and doesn't affect other copies of the card. While locked, the card also cannot be played by alternate means (ex. Worldpyre's effect) and the effect remains in other zones (it can't be played with Grasping at Shadows).

The lock effect is applied to the drawn card's game object, and remains if the card transforms. For example, when drawing a Transmute card then fulfilling its Transmute condition, it remains locked because the game doesn't consider it a new card. Plundering the card also won't unlock it.

If a card with Echo is drawn, the copy is also locked. However, cards created by drawn cards' Fate effects, such as Jotun Hurler's Snowball, are not locked.

A card with Destiny drawn by Know When to Hold 'em is immediately discarded since it cannot be played, then another card is drawn per normal Destiny rules.

July 2020's third promo quest.[1]

Know When to Hold 'em and Just Desserts are the 3rd and 4th promotional cards of Argent Depths. They were released together, with thematically related artwork featuring a character seen in the previous Friends in Low Places promo card. Their promo quest period lasted from July 20–26, 2020 and was the third of four throughout that month, an experimental departure from the normal one-per-month promo schedule.[2] They were revealed several days before their quest in Eternal's weekly newsletter.[1]
