Hey,

I have two questions - the situation is:

I have Friedrich Hemmler on table and church of sigmar. Opponent has Promenade of Malice. He mills 2 cards form my deck and one of them is another Hemmler. He then corrupted his unit and ask me to remove Hemmler from the table.

And the questions are:

- does my opponent have to pay extra 1 resource for church?

- can I protect my Hemmler on the table with Iron Discipline?

Promenade of Malice's effect is targeted ("… another target copy of the discarded card …"), so the effect of Church of Sigmar applies as usual, and you could also use Iron Discipline to protect the unit.
