Mind Collision
2

Sorcery
Target player discards two cards.
Each player puts a copy of this spell on the stack (they may choose new targets for the copies they control)
Twist on an age-old card. All the obvious uses apply (logical in Hellbent, Madness, and empty-my-hand-fast.dec), but with some benefits: plays nicely in multiplayer and has Johnny applications (Ivory Mask, Dodecapod, etc). Casting cost feels right - less card advantage than a Mind Twist for 3 at the same cmc, but with the ability to take more advantage of the drawbacks.
