Protect the Weak on Stealer of Souls seems fun. Stealer of Souls demands answers anyways.
Tocsin is good, Shaffles is despicable and should be protected at all costs. Burning one of their amber every turn is strong.
Your Sanctum spread is amazing for capturing amber (and since it's reap effects you're gaining at the same time).
Can also Protect the Weak that Briar Grubbling.
I think most turns with that deck you just want to have Sanctum creatures reaping and capturing. Your untamed and Dis cards provide board control and some additional ways of slowing your opponent down. Mostly I think you're going to be racing to get amber with reaping or playing untamed cards.
Key Hammer is strong with Murmook out since they only get 6 amber back even if they paid 7 to make the key, so they may not be able to reforge it immediately (and stuff like Shaffles helps there).
Sigil of Brotherhood lets you use all those good Sanctum creatures on a turn you're using Dis or Untamed to mess with their board state, getting you further ahead on amber.
The big risk is that they'll kill your capturing creatures and get a bunch of amber at once.
Commander Remiel has strong targets in both Dis and Untamed (Tocsin, Stealer of Souls, Bigtwig).
