Reconnaissance I feel beats Maze here. Attack all out (or just get Kaalia's trigger) and have everyone safe and ready to block. You can untap to avoid bad blockers, untap after first strike damage but before normal combat is dealt, and you can even untap after normal combat damage is dealt due to the creature being an 'attacking' creature until the end of combat step ends (you untap in the middle of this step). Being able to squeeze small amounts of damage through by attacking with everyone at no risk to your board rather than just focusing on Kaalia is worth it.

Last_Laugh all valid points made. I ended up taking it out all together though. Kind of changed some of the strategy here and now with the way i have the deck built, it doesn't hurt to have kaalia blocked, i usually sac her to razaketh because its my actual intention to win the game from that point.
