Rulings:

• 1/24/2020 The first ability of Slaughter-Priest of Mogis is a triggered ability, not an activated ability. It doesn’t allow you to sacrifice a permanent whenever you want; rather, you need some other way of sacrificing permanents, such as its second ability.
• 1/24/2020 Multiple instances of first strike on the same creature are redundant.
