The collection works like the deck builder: filters behind one button, search and buttons in one row, progress and Moondust always in view.
Other changes
Filter button in the collection with the same menu as in the deck builder: card set, class, type, rarity, cost and missing cards. The button shows how many filters are on; the menu closes with its X, a tap outside it or Escape.
New in the collection: filter by card type and by cost.
Search, Filter, Trade and the deck button now sit in one row at the top. The deck button is now called My Decks.
Base Set completion, Moondust and Grind spares stay fixed above the cards and no longer scroll away.
