No, I think you may be missing the fact that however you want to label it, if you claim that something is other than what it is, you're lying. Doesn't matter whether that part of a "strategy" or not. That's just a simple, irrefutable fact. If you tell me that the flower in your hand is blue but I can clearly see it's green, that's called a "lie."
Nothing different here. If you pick up 5 cards and claim that there are NO 2-cost support cards found therein BUT there are, then we would call that "lying." It's really pretty clear.
I'm not worried about how you're interpreting the strategy or whatever, I'm just pointing out that if you feel that it's an okay strategy for you to blatantly lie to your opponent, that's your deal. I don't plan to play that way, personally. For me it is, still, just a game and I'd like to not let winning or losing have such a huge impact on my gaming habits that I need to resort to fabrication in order to get an edge - however slight that may be.
YMMV.
