Mutiny
Oracle Text
Target creature an opponent controls deals damage equal to its power to another target creature that player controls.
Card Rulings
1/19/2018 If either or both targets are illegal when Mutiny resolves, no creature will deal or be dealt damage.
Its worst enemies are lifelink and walls.
It is one cmc but a sorcery.
I have yet to figure out whether this card is going to slightly underwhelm in my meta or straight up terrorize it.
I might be calling it early but this may very well be this Standard's equivalent to Skred.
