Journey to Nyx is about to come out an I noticed many of the websites have already priced the cards. I'm wondering if anyone has any advise on when the optimal time to pick up new cards is? I realize that these pre-release prices are somewhat arbitrary and will change. I expect many of the cards to jump in price as soon as they are released as everyone is scrambling to get them then I expect things will die down a little until the pros start making their decks at which point the cards that appear most regularly will sky-rocket. I am assuming that the best point is the trough in the middle. Is this a correct assumption and if so, when will this trough begin? I also guess that the risk here is that many cards that people think will be valuable might end up being duds and conversely, I may end up over-looking sleeper cards that no one guessed would be great cards. Am I going about this the right way or is there a better way? I would greatly appreciate any input.
**EDIT: This question has received several mixed votes on the basis that the answer is speculative. I want to make it understood that I am not asking for a specific or unanswerable question. An analogous hypothetical example to my question would be something in the vein of: When is the best time to buy electronics?
Answer: Prices generally spike right before Christmas and generally are discounted after the Holiday season and before the new models come out.
As it is not written in stone, my hypothetical question is, technically, speculative but given the fact that it happens every year I don't feel that it is an unreasonable question or unanswerable.
**I am not asking if there is a way to tell which cards will fluctuate or what price the will reach/fall to. I'm simply asking if there is, traditionally, a good time to buy new cards from a new set.
