I got to top 5 on ladder and top 64 of the latest ECQ with this list -2 Mirror Image, -1 Eilyn, Clan Mother, +2 Copperhall Bracers, +1 Svetya, Merciful Orene. The changes are to reflect a more removal-heavy metagame, but the deck is still great.
Also, damn Gozuu is a beast! I won 4 in a row and went 6-1 total at rank 2 and couldn't pass him.
