Smugglers has no luck whatsoever to it, not sure what you're talking about here.
You can draw it after your opponent's E/E/E/C/C hand or you can draw it after their $5 hand.
Every single card in Dominion has luck when you consider the luck of drawing it at the wrong vs right time. Smugglers probably feels different because wrong or right time is dependent upon what your opponent did last turn rather than what other cards you draw with it. But still, cards like Vassal, Wishing Well, Mystic, Herald, Lookout, etc; have luck in regards to what happens when you play them, which is different.
*Edit* It's not fundamentally different, really. Vassal's luck is also just "when did you draw it"... did you draw it when you had an action on top or not? But it matters that you don't find out if you're lucky under after you play the card, since playing the card is expensive (costs an action). With Smugglers, if you draw it at a bad time (when your opponent didn't buy anything you want), you can just choose to not play it and play a better terminal instead. But with Vassal, you have to make a decision without all the information. So it's not so much about luck vs not, but about how much information you have/need before making a decision.
I'm not saying that the other cards don't have luck, it just seems like more of a blind kind of luck with tournament and, admittedly to a lesser degree, with vassal and smugglers too. Obviously you can get horrible shuffle luck on any board, no matter how good you are, but with Vassal, there just seems to be more of an element that is out of our control.
Of course, this is just my opinion. I just don't love how vassal works
