Well, it's not worth ruining an expensive deck, sure. But there are other decks out there, cheap decks; nobody said you have to use (lose?) your best deck for this effect. I can get a deck of cards for about 50 cents at the dollar store (well, two for a dollar). They're either plastic cards, or used casino cards. Either way, they work quite well for the effect, and at 50 cents every time I perform the effect--that's more than worth it to me (and to the spectators, I'm sure).
But no, this won't be an effect you go table hopping with, though. I'm not really sure the whole point of the TA set was for table hopping magic, to be honest. I get a real sense of organic, on the spot (feeling) type of magic. Although, there are a few effects that are good for table hopping, this particular effect isn't one of them. Rather, this is a great effect for use when at a party or something (or a private gig).
Definitely a great effect, and I wouldn't pass up on it just because you have to destroy a deck (especially because the deck still survives, and can be used as a practice deck; or the deck can be a cheap one that isn't a big loss, anyway).
The thing is, I currently have 27 decks which can all used for that purpose. I really don't need another, or a bigger pile. Just another factor to take into account.
But again, the biggest factor for me is not being suitable for professional performances.
I had a think about this, this is another thing - unless this is your only card effect, then unless you plan to perform with plastic cards, then you can't use a cheap deck. The undesirability of switching entire deck designs in a manner so obvious cannot be underestimated. This limits its practicality again somewhat. But if you open your set with, say, Card to Mouth, then unless you want to perform Card to Mouth with your cheap deck, you can't very well perform with Bikes and then switch to a cheaper deck for this; or at least, it would be highly inadvisable.
Just some more thoughts... Feel free to disagree though
Hmm. Surely you'd still have to pull out the same deck design though.
I know that I've often spoken out against the idea that a deck can be seen by the spectator as inherently gimmicked, but surely switching deck designs, from an obviously cheap deck of cards to one that looks better, would arouse suspicion - unless you still use the same type of crappy deck as before...
I mean, if you were using random Bikes, and then suddenly took out a pack of Guardians mid performance and used them... Surely that would apply to using random cheap plastic deck, and then Bikes?
