I've never tried one, but "Juiced" decks shouldn't stand out.
I know you're relatively new to card magic, but do you object to all gimmicked cards or decks? If not, then your argument makes no sense.
Svengali Deck - let's hope no one looks closely.
Stripper Deck - let's hope no one looks closely.
ID - let's hope... you get the idea.
If you don't handle the deck in a way that makes people suspect marking, they won't go looking for it, in the relatively unlikely event that they know how to spot marks anyway. Well, unless they like browsing magic websites trying to make sure no one 'fools them' and see a post like yours, that explains it.
I'm not an expert, but I'd say that (starting from your current position of thinking marked cards are too dirty) once you've been doing magic for a while, one of three things will happen:
1. You never get over your magician's guilt. Sadly, this is very likely to hamper your performances.
2. You become a card purist and will shun everything but a perfectly straight deck. You might not even like stacks. It's a hard road to follow. The essence of magic is cheating, so why not cheat large?
3. You realise that gimmicks have their place and, properly used, people shouldn't have a clue what happened. Yes, they might say that there's got to be something funny about the cards, but that should only be because they simply can't figure out how you did the impossible. If they are specific, and say that the cards must be marked (or whatever), then you might have gone a bit wrong!
