Honorable Mention: The Elder Dragons You cant really talk about whats important to the format without the five creatures that gave it its initial name: Arcades Sabboth, Chromium, Nicol Bolas, Palladia-Mors, and Vaevictis Asmadi
16 Lands 16 lands is the energetic, less uptight (though perhaps a little less reliable) little brother of 17 lands, and probably the second most common number of lands to play in Limited
This wrath gets worse the further you are into the game, but it gets better the lower the curves of your opponents decks
Chief: Id really like to see Springleaf Drum and other ways to tap Trostani in this deck in order to help produce tokens without sending her into battle
For the aforementioned eight mana, you get an 8/8 flying vigilance Angel that is both indestructible and also provides that same indestructibility to every permanent you control
This is an ability most likely to see play in formats where you can make your creatures unblockable and protect them, which means its big for Commander, but probably wont see much use elsewhere
