Iona, Shield of Emeria does amazing things for us, one of which is auto-winning against any mono-colored deck. She also allows us to hose a third to half of any multicolored deck. Be careful what you choose! Iona is basically a removal magnet and often will get hated off the table in multiplayer. It is very important to be political about your decisions with Iona in multiplayer. Allies are very important to this deck in multiplayer, and Iona can instantly grant you allies or make enemies.In 1v1, this card is basically a auto win,She is an auto-include in all kaalia decks
Rune-Scarred Demon is a Demonic Tutor that you can cheat into play with kaalia. Cheating him into play early can grant you the exact card you need for the next attack, or maybe grab you some Lightning Greaves or a removal spell if the need arises. It can also grab our good friend Gideon Jura to make our opponents attack steps less relevant. It is also a 6/6 flier that gets better every time we re-buy it with reanimation effects. Very good and perhaps under-rated card.
If you manage to cheat Master of Cruelties in play with Kaalia and your opponent can't block him, you win. It is a one time deal though, so you must be cautious about when you go for the instant kill. After the initial attack step this guy gets a lot less relevant, but it is still a amazing blocker. I still play him because of how great he is.
Disclaimer: This combo is extremely likely to annoy other players (I think this is both a good and a bad thing.). If your play group does not like this kind of thing, You might not want to play Master of Cruelties.
Thundermaw Hellkite is one of my favorite dragons ever printed. You cannot go wrong with a 5/5 flier with an awesome ability. Thundermaw is just an enormous threat against any token strategies (dead 1/1 spirits and Emeria Angel tokens). This is our token killer. We want him against Rhys, the Redeemed, Trostani, and any other token general. He is also kind of considered to be fair in a sense where all of our other cards arent. He is great and you always want him.
Rakdos the Defilerends games very quickly. Rakdos the Defiler comes with a pseudo-annihilator ability that just closes out games. We want to play him when we have additional draw cards like Phyrexian Arena, Dark Confidant, and Underworld Connections in order to keep up with the cost of attacking with him. The only downside to Rakdos is that he is also extremely likely to annoy people. Opponents really hate playing against him (which is good for us!).
Aurelia, the Warleader ends games so quick. She gives us additional attack steps, which means even more angels, demons, and dragons! There truly isnt anything like attacking with an active Aurelia, cheating a Rune-Scarred Demon in play, tutoring for another Kaalia target, and cheating it into play during the next combat step. Aurelia is also vigilant, which means we can block! Our deck doesnt really do a lot of blocking, so be sure to block well with Aurelia.
Gisela, Blade of Goldnight literally ends games by herself. One attack with an active Gisela can net us 20, 30, 40, even 50 damage. Combine her with Aurelia and watch our deck get super dirty. Gisela is basically a win-more card. Your deck is already super powerful, so there is no problem with adding in another card that makes our guys deal double the damage. Gisela is just super nasty.
Kolaghan, the Storm's Fury is barely used outside of this deck. I get excited every time I get to play Kolaghan. He can give all of our dudes a boost, especially if we have multiple dragons in play, which is not uncommon in this deck. Combine Kolaghan, Thundermaw Hellkite, and Gisela and you get to deal a bunch more damage every turn. He also has Dash, which can be relevant against control decks or anything with many removal spells. I love this guy.
Thunder Dragon and Balefire Dragon are easily the best dragons in our deck if we are facing down any other creature deck. goblins? Thunder Dragon and Balefire Dragon deal with it. Tokens? Thunder Dragon and Balefire Dragon deal with it. Elves? Thunder Dragon and Balefire Dragon deal with it. Thunder Dragon and Balefire Dragon are the sluggers of this Commander deck. They are the best beat-sticks we can have in our hands at literally any given point of the game. These are Auto-Includes
(I combined them because they basically do the same thing in a different way)
The best card in our deck to cheat out on turn 3 or 4 is Avacyn, Angel of Hope. She gives all of our permanents indestructible. She can only be dealt with using exile effects, and by that time we are already way ahead. She also closes out games like nobodies business, especially when our opponent has no hand. I have literally nothing else to write about her. She is a must have.
