You don’t have a ton of armor gain other than Armorsmith so I wouldn’t think it would be that great.

Cult Sorcerer is the one you’re thinking about, and yes that would work.

I’d go second Piloted Shredder, Sir Finley is a super unique card.

Nothing really, it’s pretty important to this build. I mean I guess you could run Argent Squire temporarily.

That’s pretty accurate.
Muzzy's Legend C'Thun Druid (November 2016, Season 32)
I’d say Ragnaros right now, but they are pretty close.
Xixo's Malygos Druid (October 2016, Season 31)
Mulch is an option, you could also just run Acidic Swamp Ooze.

There’s 2 Fiery War Axe.
Yes.
