It sounds like you did a lot better this time. If you like Pandora, I'd suggest you stick with her. If you constantly switch masters, then you'll never get enough experience with any of them. If you don't like Pandora's play style, then switching might be a good idea.
It was only deception in this case if public information was purposefully withheld from the opponent. Which I don't know if it was or not, but it might have been, which is why I included the phrase "kind of" in my original post. (Which was super unclear. Oops.) The big thing, though, is that my original post was saying why a person might think that is was "pretty low and dirty." I posted the first two possibilities that popped into my head.
To answer your question, no, but not letting your opponent know that Obey can be used on your own models when you think that they don't know that would be deception. Like if I want them to walk into the middle of the border so that I can Obey Bad Juju up there. If I don't think they know I can do that and I don't tell them, then that would be deception. If they know I can do that, but don't think that's my plan, and I don't purposely do anything to make them think that that is not my plan, then it's not deception.
Sorry if that sounds angry. I can get... explainy sometimes, and it's hard for my to convey that through text very well.
