"In the interest of keeping World of Warcraft exciting and accessible, as more cards are released WoTLK Gold, Standard allows players to play with the latest released cards, and also the core collection of Basic as well as Classic decks," Blizzard explained in an article on its blog. "Our goal for Standard Standard is keeping the experience fresh for all our players. We also want for new players to begin playing World of Warcraft quickly, without the need to accumulate a large number of cards to make an impressive deck. Standard also allows our game designers more flexibility when creating new cards to come out in the future.
"However in the period during this Year of the Kraken, certain cards from the Classic set have shattered these objectives. When cards appear often in decks and are considered to be auto-includes deck building becomes less obtainable. The deck's variety decreases, intriguing build-around cards are pushed to the side, and the game experience becomes less engaging. Most cards should be considered an addition to a deck that is based on a situation depending on the archetype of the deck the player wants to create."
The change could cause players to desire to drop the Classic cards, however Blizzard acknowledged it was "incentivizing players to dust off their awesome Wild cards went against its aim of creating Wild amazing." In the end, it will allow players to keep their cards in the Hall of Fame set and offer them the full dust value as long as they are the highest number that can be included in one deck. The dust will be given out when it is the Year of the Mammoth begins.
Another important change is how Blizzard manages its release schedule for Adventures or expansions. The Year of the Mammoth will shift to a different schedule that buy WoTLK Classic Gold includes three expansions comprising around 130 cards. They will be available in the middle, at the beginning and the close of the year.
