I also made a kaalia deck and in mine I put Iona, Shield of Emeria. If she's in your starting hand (which happens to me like once every three draws, which is super lucky) then you bring kaalia out and Iona along with her next turn and the match is pretty much over for any mono-colored deck or a duel deck that has a lot of multi-colored cards.

Yeah, i like her, too, shes already in there bro ;)

I would take out Unexpectedly Absent or Ashes to Ashes, but only because you can get so much value out of Mimic Vat abusing ETB abilities. Depends on what you play that has value (I assume all of it has SOME value). I just know that getting the vat out allows you to take advantage of other people's dying creatures too, which is awesome.

thank u :) took ashes to ashes out, its not that great in edh

Another fun loop is Hellkite Charger or Aurelia, the Warleader with Sword of Feast and Famine and Legion's Initiative. Sword of feast and famine with the charger creates infinite attack phases. Legion's initiative with aurelia creates an extra one as the returned aurelia is "new" so it is her first attack phase again. If you find yourself with a full hand of fatties it's a great way to dump them all out.

Two GREAT cards are Dolmen Gate to protect Kaalia (cuz let's face it she's not THAT big of a creature) and Necropotence to get a big hand full of OTHER great cards.
