I'm totally with headbash guy on this one- you're hiding behind a semantical argument. Who cares if it's an exploit or trick or a psychological mindblow or the Hand of God... the only thing that matters is if the card is balanced, i.e., as 4RM3D says, if the card needs to be changed. So let's examine the card.
It's got a woeful floor (7 Gold power), a decent average value (22 Gold but -1 CA and 1 Bronze Card value), while having an excellent ceiling of 22 uncountered power. On the other hand, it's not a wholly unawkward card to play, since CA is most important in R2, and has severely diminished value in R3. Thus, it's best played in R3, very meh in R2 unless you're trying to 2-0, and fairly meh to play in R1 because the Bronze likely gives your opponent better options (unlike when you're very shorthanded).
If you're getting yourself into a situation where he gets to play his 22 Tibor for free you've probably misplayed or applied insufficient pressure to minimise the effect of his Tibor, unless he literally topdecks it or gains access to it in R3, where Tibor truly excels. And it's not like the Mill archetype (where decks actually employ Tibor for a free 22 power) is not predictable at all, and doesn't allow for counterplay.
Case in point, I had a game last week where I was playing against Mill as ST with resilience, and I drew nothing going into R3, only holding a dead D-Bomb. He had 2 cards against mine. I still had access to ST passive, so I chose to go first (just to show my opponent I knew what I was doing, and instantly passed with 22 power on board. He had yet to play Cahir and Tibor, so the pass completely limits his options and what he planned to do, and he forfeited on the spot.
Predictability allows for counterplay, and these cards have an inbuilt way to counter them.
