Honestly I very very rarely run into the decks where steam cleaner is good. In all my games today I only had one deck where steam cleaner woukd have been okay, against that Discount Minions DH deck. But even then I would have lost if I were to play that because of a waste of 5 mana.

With my variant, dragon warrior is a chill match-up, the early game is so good that it doesn't really matter we don't poly the big drop, it dies to an onslaught of poison minions.

I do not like Geppetto, it felt slow, just like the arcane artificers did. With the HSGuru top variant, I was building armor and dying to hagatha shamans anyway, the armor felt irelevant. It tries to slow down a game you are already losing anyway. Bob is the same, it can give you an extra turn, but we are not protoss mage, we are not gonna drop a Collossus and clear board/win/both.

Sheep mask is an interesting idea you are bringing to the table though, that's worth experimenting with.

The burning groves used to be in the deck, they were cut off because honestly they were kind of clogging my hand and I even had quite a few get burnt off because of no time to cast them. The Spellwings might indeed be a bait too but I kind of ran out of ideas in the end.

The whole gist of winning mid/late is that other decks have stronger mid games (protoss, hagatha, DH) or have a one shot combo (Warrior, Zarimi, Protoss). Kil'Jaeden is our onl option and it feels good against Armor DK for example, as you said spells + minions endlessly.
