Hey! Nice deck, cool idea.
A few cards that come to mind are:
Burglar RatUnburden - has the advantage of cycling if you haven't hit a caress yet.
Fell Spectre and
Raiders Wake are both good too. They both have the same effect as the caress but also force discard at the same time, either repeatedly (
Raiders Wake) or with a flyer on deck too (Fell Spectre)
Also, not really sure what
Blightbeetle or
Scar are doing in there, unless there is a meta reason for it.
