Buff Neurotoxin (creature targeting)

[OdinVanguard]

So right now, neurotoxin only affects players. There is really not much point in having multiple in a deck other than getting one earlier, which is kind of annoying for a spell effect.
It would be neat if the effect could target creatures as well.
A creature with neurotoxin on it would get +1 poison anytime the owner activates its ability.

Simple subtle buff, but adds some utility for dealing with annoying growers, etc...
Could also be very intersting in gravity or voodoo decks.

[Chapuz]

Increment poison when the owner draws a card, that would be neat.
Voodoo and Matyr (so far) have direct synergies.

[Zaranir]

I'm for it, at least there will be any reason to use the 2. of it somehow.

Neurotoxin's self redundancy is awkard by intentional design
