The more people in the game, the more opportunities for your werewolves to transform each turn cycle, so werewolves that have beneficial transformation triggers like Huntmaster of the Fells and Afflicted Deserter provide more value for you
While there are some chaos cards, the idea behind the deck is more of just to make stuff happen
Cards like Murmuring Mystic, Sprite Dragon, Third Path Iconoclast, and Guttersnipe are excellent additions to any deck that focuses on non-creature spells
Id personally trade an original version of Watery Grave (from Ravnica: City of Guilds) for six copies of the newer one (from Guilds of Ravnica or Gatecrash) but thats because I have an ever-increasing supply of decks
I hope that you are having just the best day today
(T+2) Extra turn 5: Tutor Kozilek, Butcher of Truth, or Ulamog, the Infinite Gyre (but do not cast them!), instead cast Time Stretch a 4th time
