But I prefer my idea: instants and sorceries with an alternative form of scavenge that lets you turn them into Witherblooms ubiquitous Pests
Lets exclude all gold cards, hybrid cards, or white double-faced cards that transform into cards of other colors (sorry Brutal Cathar/Moonrage Brute)
It remains to be seen how much of this flagship product gets printed, but suffice to say any valuable cards opened from the set has the potential to remain relevant for a long time
Similarly, a [X] cost becomes "Reduce enchanted creature's toughness by X." You can't pay a cost that would reduce enchanted creature's toughness to less than 0
Card not found from Innistrad (2011) is another one of those cards that brings nice inevitability to the game, as you casting an X-spell twice will eat huge chunks of the target players life
A fun deck, to be sure, but will not be tournament quality and that is OK.
