Grim Haruspex is something, and Murderous Cut is awesome, but the mana is actually worse than the white or red splash
So even in the deep pool of Zombie one-drops, this new guy makes a very big splash
It doesn't destroy anything, so it's kinda sorta less effective than Demolition Field, but is also more inherently card advantageous than Volatile Fault
My initial take on the mechanic was for it to be an instant or sorcery, but you could pay mana to turn it into a creature
All this synergy lets you go wild with other abilities that can pump up your creatures, letting you attack with a huge army for relatively little mana
For example, a persist creature like Putrid Goblin, First Day of Class, and a free sacrifice outlet let you sacrifice the Goblin as many times as you like
