I suck at StS. I play the mobile version on my phone every so often but I'm usually lucky if I even reach the heart, never mind defeating it. Part of the problem is that my favorite is Silent, specifically shiv build Silent. I try to force my way to that no matter what cards or relics I get, which rarely works out.
But yeah, Silent.
