I didn't intend for the card to create the Antimatter effect, but you bring up a good point, rickerd. If I am to change it to -2 to +3, I need to specify that it can't reduce attack below 0.
@Mathematistic: I made sure the theme stayed Aetherific. Basically the souls of the dead are drawn to this dimension like magnets instead of to the realm of the dead, and yes it's meant to be used with Sparks and just CC in general.
I saw no need to specify percentages since that'd be up to Zanz if he wanted to introduce the card anyway. I imagine something like 60% Warped, 40% Spark for the unupped, 70% Warped, 30% Spark for the upped, and 40%|30% chance to lower stats.
Dead Sparks would behave like regular Sparks and trigger death effects because that's what they're intended to be used for.
