Echo

Echo
Repeatable the turn you play this.

An Echo copy of Warpath.

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 Unstable Evolution, and officially debuted in The Witchwood.

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

Notes

• 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 Summoning Portal or Sorcerer's Apprentice).
  • Example: If Dire Frenzy is played on Hunting 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 Scroll 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 Warpath to destroy Mecha'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.

Cards with the Echo mechanic

When Echo was announced, Blizzard confirmed they would not be modifying already-existing cards to have the updated keyword because the mechanics are not completely identical to Echo. The following cards have the mechanic without the keyword.

History

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.

Trivia

• Although Blizzard did not add Echo to Unstable Evolution or Witch's Brew, it was given to SN1P-SN4P. This is likely because SN1P-SN4P will rotate out of Standard alongside the other Echo cards, meaning there won't be any confusion.

Patch changes

• Patch 16.0.0.37060 (2019-12-05): Copies of cards with the Echo keyword can no longer cost less than (1).
• Patch 11.0.0.23966 (2018-04-10): Added.
