Hi,
I saw your question on Vileplume and Lucario GL and I was unsatisfied by the answers because I was quite sure that this is false. So I asked this at official Organized Play Forum.
"There was an interesting ruling question for unlimited regarding Vileplume from BCR and Lucario GL.
[...]
Now I want to forward this question to this forum because I'm interested in the answer (imo the answer at pokebeach is not right but I'm unsure).
I guess it's something like 'new is always better'. So the effect which comes later into play counts but as I said I'm very unsure."
And here is the answer I got from Pokepop:
"Well, there are two ways that one could go with it, and neither of them are the 'rule' that was given in PokeBeach. That was totally wrong. If anything, it is the opposite. The person whose Pokemon is being affected usually chooses the order if they are effects taking place at the same time.
And that's what I'm thinking would apply.
However, one could make an argument for 'last played' taking precedence. But, these are both 'continual' effects. They are constantly being applied and are not triggered. Given that, I'm leaning toward them being something that the player whose Pokemon is being affected would get to choose the order. And that would be the Defending player.
Of course, this situation will never come up in a real game."
I'm writing you that you can fill it into your thread because I have no rights to answer in this section.
Kind regards,
Fiete
