Events are their own thing now, and they stop skewing the meta

Clash Royale game modes are played as different games. A river race battle only somewhat resembles Trophy Road, and neither tells you much about Path of Legends - and in some modes you do not even pick your deck. Elixir had one blunt fold for this, keyed on the battle's type, and it was quietly wrong: the API files everything from a two-week 2v2 tournament to the reworked Seasonal Trophy Road under one type, 'trail', which Elixir called 'casual'. So the Seasonal Road - a real ladder, but one that bans your best eight cards and floors the rest at level 15 - was being counted as casual play, and its level-16 decks were informing what Elixir told you about decks generally. The fix is the API's own marker: a battle played inside a time-bound event carries an eventTag, and nothing else does - 100% of those 123,562 battles against 0% of every permanent format. Event content is now its own mode group, mode: 'event' selects it, every other mode excludes it, and the meta ignores it entirely along with any deck you did not choose yourself. It is all still there to read battle by battle; it just no longer speaks for the game. Contract 6.17.0.
