Pretty good against AI3. It works against T50; there are better decks out there for T50, but this is lots of fun.
Really? It looks like it would quickly become very boring to play. I can't stand playing the same deck for very long, the exception being mutation/fate decks (can't wait for the tournament coming up, though the pillar count in the assigned deck seems oddly low). I just get bored. It's why I sold all my cards from puppychow's rainbow and made a RoL. My brain was hurting and the games were taking too long. RoL is just simpler, fairly fun to play, and makes me excercise my brain muscles (calculating damage for EM).
Like money-man said, eclipses might be worth considering in this deck.
