Hearthstone is about to receive its first expansion of the new season, and that means a changeover in Standard format play marked by a new year. This will be the Year of the Hydra, and Blizzard has announced some big changes to the Core Set. And this year’s Core Set will be bigger than before, and include the legendary treasure-hunting idiot, Reno Jackson. The rest of the League of Explorers will be there too, but folks, Reno! Jackson!

When the Year of the Hydra launches on April 12 with the Voyage to the Sunken City expansion, the Core Set will grow to a whopping 250 cards–57 being rotated out and 72 others rotated in, making the set 15 cards larger than last year. That date will also cycle out Ashes of Outland, Scholomance Academy, and Madness at the Darkmoon Faire, to make room for the new year of content.

The most significant inclusion in the new year is the return of the League of Explorers, the fan-favorite breakout characters who were also introduced in an adventure of the same name. Those cards had huge effects that will return for this year’s: Brann’s battlecry-doubling effect, Sir Finley’s hero power switching, Elise’s card-generating, and of course, Reno’s full heal. Other notable returns include Wild Pyromancer and Acolyte of Pain for a powerful card draw combo, and the Druid legendary Fandral Staghelm.
