Question regarding Volrath, Spark Double, Joo Dee and a Planeswalker
Okay I think this is a slightly wild one but it is probably pretty straightforward to people who know copy rules a bit better than I do.
So let's say I have a [[Volrath, the Shapestealer]], a [[Joo Dee, One of Many]] with a counter on it, a [[Spark Double]] with a counter on it copying whatever creature, and a Planeswalker of any kind.
Step 1, I make Volrath a copy of Joo Dee, I now have a 7/5 with the Joo Dee ability and the Volrath ability.
Step 2, I activate Volrath's Joo Dee ability and put it on the stack.
Step 3, I activate Volrath's ability to become a copy of the Spark Double.
Step 4, I allow the Joo Dee ability on the stack to resolve, creating a copy of Spark Double (except 7/5 with Volrath's activated ability for the time being). The Spark Double enters, and I choose to copy the Planeswalker.
Does this result in, effectively, a perfectly normal Spark Double with no additional text or abilities given from Volrath? I am unsure, but I assume the Spark Double doesn't keep Volrath's activated ability because it's become a copy of the Planeswalker and the Spark Double ability doesn't have the rider of keeping Volrath's activated ability or Power/Toughness?
