As of the 22nd of October, both Team Arenas and Hero Battles have been removed from the game. Builds specific to either arena have been archived, and builds with multiple tags had their TA/HB tags removed. Obviously, this means we will not be taking any more TA or HB builds onto PvX.
But when something leaves, something often replaces it. In this case we have been given Sealed Deck, in the form of the Codex Arena. Anybody who would like to expand the following portal may do as they wish and any positive contributions towards it will be appreciated. However for this play type we will not be accepting builds due to the nature of the arena, with decks changing every day. We would like to also promote some build making in an area where creativity shines.
