player choice really, not as strict an equation, if necrovalley was guaranteed to stay on field throughout the entire game gks and decks which go around them would be the only ones in the format. That being said the lack of Dark Hole is more alarming. And don't say "I'll always have a monster on the field" you won't and you know it. Btw, how about BoM? Apart from all its other uses, tomato to spy and bom or spy flip and bom is always fun stuff, especially if the opponent wants to attack that face up spy. Also, allure? And maybe Caius, all the cool kids like Caius, and you can make locomotion and stuff with it, only the very cool kids like locomotion.
