One of the really exciting things about this list, in my mind, is the four copies of Mutavault
If you control Tom Bombadil with at least 4 damage on it as well as a single Saga which has four or more lore counters on it, and that Saga leaves the battlefield later in the turn, Tom Bombadil will be destroyed
Convoke things, sac the convokers, and go
If you cast two spells during the turn, you get 3 life, and if you cast five spells, you get 15 life
Most likely if youre playing the Rakdos or Jund versions of this deck, youre probably winning through creature beats, or your playing Hellkite Tyrant
Then when it dies you gain life equal to its power, which could be quite a bit here and there
