I've been trying to avoid adding more double-sided cards into my cube over the last few years, I think the only exception I've made is for Fable of the Mirror Breaker, but Cecil is very intriguing on the front side (and also one of my favorite protagonists from the series) so I'll probably give it a run.

Flipping into a 4/4 Lifelink is massive, I would have preferred it if it wasn't quite that beefy, but it might be fine since there should be enough of a window to answer it before the flip if you were to start with it on T1.
