Casts When Drawn

Casts When Drawn is an ability on spells which activates when the spell is drawn from the deck, causing the spell to be cast instantly, without spending any Mana. After it resolves, the player draws another card to replace the cast spell in their hand so that they do not miss their draw.

Casts When Drawn is featured exclusively on spells that are shuffled into a player's deck via other cards. Some cards with Casts When Drawn are shuffled into the opponent's deck, with negative effects once drawn; other cards are shuffled into the player's own deck, with positive effects for the player.

Casts When Drawn is distinguished from general draw-related triggered effects, which activate when any card is drawn.

Strategy

 * Due to the nature of card draw, Casts When Drawn cards are difficult to predict or prevent. This can make it hard to plan around their useful effects, or give the player a chance to evade their drawbacks.
 * There are a few ways players can avoid activating enemy on-draw effects that have been shuffled into their decks. Tracking is particularly useful for this, neutralizing any on-draw effects displayed. However, the most common way is to intentionally maintain a full hand, causing any further cards to be overdrawn. While drastic, this can be an effective strategy and in the right circumstances a desirable trade off, such as if facing lethal from a Burrowing Mine while the opponent's hand and board are empty. This is most viable for control decks, and is especially relevant for Freeze Mages trying to prevent a Burrowing Mine from circumventing their Ice Block. More aggressively, Fel Reaver can be intentionally employed to mill the player's own deck.

Trivia

 * Before Patch 12.2.0.26996 added the Casts When Drawn keyword, cards with this ability featured text with the same format: ". Draw a card. Cast this when drawn."

Patch changes
