Repeatable the turn you play this. Copies can't cost less than (1).

An Echo copy of The WitchwoodWarpath.

Echo is an ability whereby the card can be played multiple times in one turn. This is accomplished through copying the card to the user's hand until the end of their turn. It was informally introduced in Kobolds & Catacombs as Kobolds & CatacombsUnstable Evolution, and officially debuted in The Witchwood.

Echo copies have a blue glow and black smoke around them.


  • Echo works by placing a new copy of the card into your hand, which is removed at the end of your turn.
    • This effect is triggered by echoed copies as well, meaning that you may keep deploying until you run out of mana.
  • Echoed copies are always the original version of the card. Copies will not take in-hand stat or cost changes, unless it's being provided by an aura (like LegacySummoning Portal or LegacySorcerer's Apprentice).
    • Example: If The WitchwoodDire Frenzy is played on The WitchwoodHunting Mastiff and a buffed Hunting Mastiff is later drawn and played, the first Hunting Mastiff will receive the +3/+3 buff but the rest of the Hunting Mastiffs played using Echo will not receive the buff.
  • If a spell with Echo is cast by another card such as Yogg-Saron or Kobolds & CatacombsScroll of Wonder, you will not get another copy to your hand, because Echo cards must be played in order to receive a copy.
  • Echo is resolved after Deathrattles.
    • Example: Using The WitchwoodWarpath to destroy The Boomsday ProjectMecha'thun with an empty hand and deck will successfully destroy the opposing hero.
  • The mana cost of Echo cards cannot be reduced below 1 mana.

Repeatable this turn[]

When Echo was announced, Blizzard confirmed[1] they would not be modifying already-existing cards to have the updated keyword because the mechanics are not completely identical to Echo. Nevertheless, the Kobolds & CatacombsUnstable Evolution was eventually changed, probably because of a potentially broken combination with Voyage to the Sunken CityRadiance of Azshara.

"Repeatable this turn" cards function otherwise exactly the same as Echo cards, except the fact that their cost can be reduced to 0, and they don't trigger the effects of Echo-related cards such as The WitchwoodMistwraith.

The following cards have the mechanic without the keyword.

Echo was inspired by "Ghostly", an earlier mechanic experimented with during the development of The Witchwood, when the expansion was instead called Murder on the Gilnean Express. Cards with Ghostly discarded themselves at the end of the player's turn. Cards that only had Ghostly as their card text essentially required the player to play the card the turn it was drawn, while other cards added Ghostly copies of themselves to the player's hand. As Blizzard kept iterating, they found that the most fun version of Ghostly was the cards that replicated themselves, as they could both be useful during the early game and could be powerful during the late game if the player sunk extra mana into them. Furthermore, deciding how long to hold on to them to eke out more value proved to be skill-testing and interesting. As the setting of the expansion evolved from a train to a haunted forest, Ghostly "became more and more the perfect flavor for the set", eventually becoming Echo.[2]


  • Although Blizzard did not add Echo to Rise of ShadowsWitch's Brew, it was given to The Boomsday ProjectSN1P-SN4P. This is likely because SN1P-SN4P rotated out of Standard alongside the other Echo cards, meaning there wouldn't be any confusion.
  • Prior to Echo's nerf, it was possible to play infinite copies of an Echo card in a single turn if there was a cost reduction effect for both the original card and its subsequent copies, such as Echo spells being reduced to 0 mana by LegacyMillhouse Manastorm. SN1P-SN4P was a notable offender for this condition as its Magnetic meant that it was possible to play infinite SN1P-SN4Ps without running out of board space. This was the reason that The Boomsday ProjectReckless Experimenter was nerfed to be unable to reduce Deathrattle minions below 1 (as SN1P-SN4P also has Deathrattle), but SN1P-SN4P Warlock managed to do so anyway by using Goblins vs GnomesMechwarper and LegacySummoning Portal to play as many SN1P-SN4Ps as possible in a single turn, an exploit so prominent that it was the reason that Echo was nerfed in the first place. With its limitation already applied to all Echo cards, Reckless Experimenter's nerf was reverted as well.
    • "Repeatable this turn" cards are unaffected by the Echo nerf so they can still be played indefinitely. However, this interaction can still be seen upon somehow gaining a LegacySorcerer's Apprentice or Journey to Un'GoroRadiant Elemental.
