@ Jamie: I have not decided yet. I really enjoyed Gitaxian Probe + Cabal Therapy + Empty the Warrens, this combination won me a couple of games during the GP Lille trial. But during GP Kyoto I cast Empty the Warrens only once against miracles and Ad Nauseam 3 times in total during the entire main event (13 rounds of swiss + quarter final + semi final -> 15 rounds, around 35 games).
