This card's ability seems OP for the above reasons and doesn't fit the Aether theme quite well either.
I know no one really wants to, but consider PvE. The AI wouldn't recognize the difference.
The +1|-1 goes to whoever comes in contact with the Adder. What if it were a 10% chance to delay instead?
How does it feel like ?And I was thinking that, as the name says, it shocks the creature. In doing so, it stimulates muscles while causing them to deteriorate. And the delay comes from a slight chance of paralysis. And it's not only meant for CC, but to boost your own creatures. See this with Voodoo Dolls and whatnot.
