Kykar's Token Engine (EDH / Commander)

Kykar is an excellent commander because for every noncreature spell you cast, you get a 1/1 flyer that you can sacrifice for mana even if you don't have one of the altars. This deck is designed to take advantage of the noncreature nature of Kykar and as such only has 6 creatures in the deck. Just so we're clear, this isn't an aggro deck, the only time you should really worry about attacking is if you have Narset, Enlightened Master or Sword of the Animist on the field. Because you're constantly getting tokens that you can sac for mana, this deck can go ridiculously fast if you play smart and get lucky.
Some key cards in the deck that enable you to win are A) Anointed Procession, which doubles your created tokens which gives you extra extra value for each noncreature spell you cast; B) Ashnod's Altar/Phyrexian Altar, both of which allow you to sacrifice any creatures, not just spirits for double colorless or one of any color respectively; and finally C) Skullclamp, which allows you to turn creatures and a little bit of mana into card-draw.
Going through the deck, you'll notice that there aren't very many dawdling cards; pretty much every card is in here to keep you moving forward, whether it be ramp, token generators, or card draw. Other than that, pretty much everything's removal.
One last note, this was the first commander deck I ever completed, so going back you'll see plenty of god-awful earlier versions of the deck. Just know that obviously I've learned a lot about the format since then.
