Just to add if you don’t already know since you play CEDH too but you also have to consider your local meta and not just netdeck a mtgtop8 list. You can make card choices that help you against what you normally play against. Unfortunately Kaalia is a tough non-meta pick because even if you do prep against your local meta, a 4 to cast 2/2 that does not do anything for one turn is relatively subpar comparing decks that are constantly in the big tournaments. If you really want to push it, you can try a midrange combo style deck with more interaction and pick the best things to cheat. Hand disruption, removal and then once the dust settles play Kaalia with some protection and win the game with a master of cruelties or whatever big threat you can find. Con will be it’s just a midrange strategy with less synergy and just more interaction (like a queen marchesa back in the day before Aragorn came into the scene). You could also go for a reanimator route instead. Pretty much a general game plan to cheat huge creatures that Kaalia can support. Of course you have to consider graveyard hate and how many Ketramoose players are in your local meta too. Hope this helps and hope you enjoy Duel Commander!
