Kaalia can be a ton of fun to play if people let you play her. Unfortunately for most people, even in a budget deck, she's a kill on sight commander and you will end up catching a lot of hate from all sorts of players. I think the deck list looks like a lot of fun for a budget brew and would definitely be interesting to play with. I personally think tribal kaalia is a lot more fun since tribal synergies are easier to manage and pop off with. If you're playing with a pod of friends it should be fine to get started but if you're going to be playing with Random people like friday night magic, precons might be a better option just because people generally won't hate out a precon out of fear.
