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?
Hilarious that Nadu, designed for Commander but released in a Modern set, is now banned in Commander too (after it's collateral damage in Modern).
Kinda do not agree with the fast mana bans :-/ I understand their reasoning but I haven't thought they were banworthy at all.
