Toxicroak and De-evolving

[Scyther_trainer]

I know that Toxicroak's Poison Sacs poke-body prevents your opponent from removing poison when your opponent evolves or levels-up, but what about when you de-evolve their active? Like with Dialga's Flash Cannon?

The Spoiler for Poison Sac says:
"You opponent’s Poisoned Pokemon remain Poisoned even if they Evolve, Devolve, or Level-Up."

Thanks in advance! :biggrin:

It says right on the card that it prevents devolving from removing the Special Condition Poisoned. I'm not sure why there is a question here. Did I miss something?
