Indeed! You also donāt need the hero that normally casts the spell out, so you could have still brought Oni out. You would have had to suicide Bigby to do it, and itās possible I would still win out, but it certainly would have severely crippled my offensive capabilities, and bought you a good deal of space to go to tech 3 (where Truthās primary win condition lies)
Free Speech is insanely useful for that very abilitiy. No Zane Haste, no Garth fetch on maxband, No Drakk Frenzy or Haste, no Sparkshot, Readiness, Two Lives, Sword runes from Grave, Swift Strike, Invisibility from Vandy, etc etcā¦ Very powerful
Indeed, It is [Demon]/Necro/Finesse. I think Dreamfire or Zhavier coined the name for the deck when I was playing it and finding a lot of tournament success. It has a lot of different win conditions, the easiest being Graveyard + Finesse Tech 2. Combined with Garth to fetch a Grounded Guide or Maestro, buffed / free fencers from Graveyard and Dark Pact to bring Star-Crossed Starlet to join is very oppressive. You can also run usual Demon or Necro gameplans (Metamorphosis, Gargoyles + two-step, Zarramonde, Lichās Bargain + Bone Collectors, etc), and some crazy T0 Vandy + River shenanigans (Dark Pact + Harmony + Discord / Two Step early on is nasssty)
Main weakness of the deck is no upgrade removal.
The only other decks people have an alternative name for, AFAIK, are:
420 Blazeit - This refers to a [White]/Peace/Finesse deck that has a gimmick infinite combo. You run Peace Tech2, and work towards getting 2x Drill Sergeant + Maxband River, then getting Smoker in hand. River plays smoker for free, and one of the DS can target Smoker with a buff rune to send it back to hand. Thus, infinite +1/1 runes for units. Usually Strength is the White choice, for Birds Nest
Miracle Grow - what I started calling Anarchy/Strength/Growth. Main win condition is Might of Leaf and Claw, activated by Zane, Surprise Attack, and just red starter deck stuff in general (not to mention Birds from Birdās Nest). Also operates well on Blooming Ancients, Strength T2 + Arg buffs, or Anarchy T3, in case the opponent doesnāt have upgrade removal (many decks donāt!)
