I think the adaptation of pyromancer alongside equality would be great, but not in this type of deck. You seem to have a lot of 1/1 silverhand recruits on the board, and pyro does not work too great with that, alongside getting big buffed minions. It might just be a dead card. I would recommend either dropping the buffing of your dudes, or of the pyromancer combo and add consecrate or some other defensive tool. I do really like the deck and its direction though, and I am open to be proven wrong if it turns out you can  squeeze out enough value.

Tol'vir Stoneshaper does not count as a played Taunt minion. You don't have enough Taunt minions in your deck to even complete the quest. I recommend reworking it a little, and fitting in a few more Taunt minions. Maybe Tar Lord for some beef, or Stonehill Defender for some Taunt value.

Can someone confirm if this is a deathrattle? It says when it dies which is oddly out of place from just using the keyword. Is the wording different on purpose, or is this just a mistake?

I would take two Mad Scientists over the haunting creeper in this deck. More value I think.

Warlock can clear all of that with 1 card.

Except you died on the turn after you played Tyrantus because he has no impact on the board and your opponent is free to punch you in the face. Your proposed combos mostly double down on getting your face punched.

Living Mana uses the same 'when they die' and its tokens are deathrattles, so this should be the same.

Bro its a theorycrafting deck for a future expansion, nothing wrong with thinking outside the box.

I would suggest you look at what our control decks actually look like right now, than try to reinvent the wheel. There are several to choose from. You could look at a Zeus deck like Savjz popularized on his stream, although without Ancestor's Call that list will look much different in standard.. Varanis? from Fade2Karma is known for laddering with, and streaming control shaman. There is also a dragon control list by PRIMO (I think he goes by something else here, but I can't remember off hand). Find one of those decks. They are actually solid decks. Then make adjustments for standard.

So if you compare this to Mark of the Wild you have to buff a demon and you are only getting +1/+1 extra stats at the cost of giving your opponent a mana crystal? Nah i'm good.
