 The DCI (formerly Duelists' Convocation International) used Elo ratings for tournaments of "" and other Wizards of the Coast games.However, the DCI abandoned this system in 2012 in favour of a new cumulative system of "Planeswalker Points", chiefly because of the above-noted concern that Elo encourages highly rated players to avoid playing to "protect their rating".Pokémon USA uses the Elo system to rank its TCG organized play competitors.
