In the compendium of The International 2017 there are 64 characters who claim to receive the Arcana rarity set. The voting does not involve 11 heroes who already have such sets, and another 38 were eliminated during the voting.

For each round of voting, one week is allocated. Lina, Legion Commander, Terrorblade, Techies, Shadow Fiend, Phantom Assassin, Crystal Maiden, Zeus, Monkey King and Juggernaut do not participate in the vote, because they already have Arcana sets. Valve also released an extraordinary set for the finalist last year’s vote: Arcana on Io can be obtained for reaching the 245 level of the Combat Pass. It can not be bought or exchanged.
