Random Generator gave me Lifeforce and Demonic Hordes. Another color-hoser, which sadens me, but swinging it so the caster gets hosed seems fair. Pro tip: In group games, Sleight of Mind the word black on Demonic Force to a color you would like your opponents to be countering.

Wow, I'm not at all sure who comes out ahead with this. If the opponent is at all ahead, they can lock you out of the game for several turns. On the other hand, you will quickly decimate their mana base.

Also scary as a reanimation target (but then lots of things are).

Yeah, it does do a fair Standstill impression (albeit, much more expensive). I pushed the black a little harder on purpose, but I could see some players following this up with very splashable cards (like Fireball) or artifacts. Still, that is a scary drawback, eh? I'm still not sold if the card would be fun to play, but I'd definitely give it a shot.

Intriguing!
