A card you may want to consider is Reconnaissance It's good protection for Kaalia when and if she deals substantially larger flyers.To sum it up visually: "I attack with Kaalia" "I block with my 6/6 flyer" Untaps kaalia "Nevermind. Oh hey, Avacyn doing here?"

DFall3n1 I actually use Maze of Ith for this. Definitely not a bad card though, might consider it but, space is kind of tight right now.

Reconnaisance is better than a land that doesn't tap for mana any day. it can untap your cretures after damage in the end of combat step.

Chandra585 fair point. I was actually speaking with Phil, Dog, Nine Tails and AZ earlier on our kaalia discord. We're straying away from being a combat based build of her. I did end up taking out maze as it was essentially missing a land drop, though it was good at stopping opponents commanders swinging or other problems.
