Olivier Ruel (born 24 July 1981[5] in Aubervilliers, France) is one of the most successful professional Magic: The Gathering players.

After a mid-table result there he teamed up with his brother and Florent Jeudon for Pro Tour Washington D.C., going under the name of "Phenome J".

They finished eleventh at the Pro Tour and quickly followed that up with a victory at Grand Prix Cannes, now going as "Black Ops".

Again Black Ops prevailed defeating Game Empire consisting of Alan Comer, Brian Selden, and Kurt Burgner as well as the Antarctica-team of Jon Finkel, O'Mahoney-Schwartz brothers.

[6] Their first major individual success came several months later when the Ruel brothers met in the final of Grand Prix Porto where Antoine defeated Olivier.
