The destroy target creature one is interesting. My regex isn’t good enough to get this in one nice query but it looks like there are 3 cards that have just this rules text:
- Eviscerate - 3B
- Impale - 2BB
- Murder - 1BB
If it’s a black card I can’t imagine they go BB on it, but maybe BBB for some kind of lore reason. Maybe it’s 4B for limited?
My other thought is that it’s in a new color or color combo. Maybe a new 1BW murder?
These are so nice, reminds me of the seasonal Mishra’s Factory and Urza lands from Antiquities
