What’s new

Big update

The Rival League, skins and new menus

  • Play rated games against other people in the new Rival League: a Find match game is rated when at least two signed-in players are at the table.
  • The Rival League opens with Season 2 on November 16. Until then, rated games already shape your starting rating.

Small patch

Hand picks and rare card previews

  • Elites and bosses use powers such as Royal Decree and Scorching Breath on a countdown you can watch. Earn up to three stars in each match from its star goals, and choose a boon after each boss.
  • Follow the story through voiced cutscenes and an opening and ending film, guided by Llamacorn, who seems very keen to look after the Shards.
  • Restore the Rainbow on each difficulty to earn the Shardbearer, Rainbow Champion, and Unstable Legend frames. Equip them in the Trophy Room.

Big update

Your table, your pace

  • Race to grab your starting Baby Unicorn: everyone chooses together, and the first claim wins. Unclaimed seats receive a random Baby when time runs out; pass-and-play still hands the screen over one player at a time.

  • Press Space to pass in a response window. Change the key or disable it in Keyboard shortcuts. Accessibility and Table theme now have their own pages in the options menu.
  • Home features a different card set for each browser session, including Dragons and Unicorns of Legend. Summoning Ritual occasionally comes to life, and your character jumps in whenever you return Home; reduced motion keeps them still.
  • Lighter live updates use less data, returning visits reuse artwork and audio, and follow-up choice banners transition more smoothly.

  • Home fits better on phones, with easier scrolling and lighter opening animations. Avatars stay visible above their glow, and the language picker now includes flags.
  • Flying Unicorn sacrifices and destruction now complete their follow-up effects. Optional choices such as Rainbow Mane can be declined, bots handle Tiny Stable better, and Quick Battle uses medium difficulty.
  • Crew controls fit narrow lobbies, solo games against bots skip the Save as crew prompt, and returning Home from results clears old saved seats.
  • On desktop, your unicorn celebrates unread releases with a rainbow beam. It plays once per update and respects reduced motion; the unread dot clears when you open Releases.

Small patch

Cleaner deck artwork and release navigation

  • Deck and expansion boxes now appear without white backgrounds and with consistent sizing in the lobby and deck catalog.
  • Box artwork stays clear in both light and dark themes.
