"Divergent Transformations:Tokens to Kings"
Virgilio F. De leon Jr. MD
I used to have a Proteus Staff deck that consistently churned out a Darksteel Colossus(Blightsteel wasn't around yet) in exchange for sacrificing a 0/1 Pest token. For the cost of 3 mana the conversion of a lowly token to a massive beater is worth it won't you say?
Divergent Transformations from the new Commander 2016 gives you that same option and at Instant speed too. It is part of the Undaunted spell cycle and it thrives on the fact that you have to kill. It actually costs 1 colorless mana less for each opponent. Making this a possible 4 to cast spell if you have 3 opponents.
So what happens is that you exile 2 target creatures , it's controller reveals the top of his or her library until they reveal a creature card and put it directly into the battlefield. 2 creatures that come from tokens to become kings. Control decks that feature big creatures would welcome this spell especially the Temur or Jeskai colored decks. In the Yidris decks where he deals damage and the next spell you cast imagine all sorts of card advantage that this could carry.
