Going to draft the cube tomorrow, so I finally got around to throw in Skyfisher Spider. I am thrilled to have this card in the cube as it is doing everything Golgari wants.
I'm a little sad to see Herald go, as it works as a 23rd card in three archetypes, but if I am being honest, it was always the 25th card. Three decks could use it, but none wanted to, so farewell little spork! You could do many jobs, but none of them particularly well.
As for Spiteful Prankster, I hope it does not mislead people into thinking there is more support for sacrifice than there actually is... It's more meant to replace Hero of the Games as a payoff for going wide.
