Well, I am ambivalent to it and will not buy one myself
1) They are solid decks.
1a) But the price... um, well... too high by straight value card-for-card BUT you pay for having those fitting cards.
2) It would be worse if there were really great cards inside - the price of those cards would plummet as there is a guaranteed supply.
2a) No rares were harmed in the making of these packs
3) The idea is copied from other TCGs... which is fine. But sorry, "theme" does not really carry much here, not as in, say, Magic's theme decks. That's largely due to UR not really being comparable to Magic in many aspects.
=> I think it is a good choice for new players... maybe, if they don't want to invest more. For everybody who has a functioning deck, these new sets are clearly not the way to go. It may indeed be the right way to grab new players more easily... I myself don't fall into the category this is aimed at at all. (I do read manuals, for example, a seriously outdated thing to read.
). It has a very slight air of money grab. Then again, you pay for pre-construct service and nobody hinders player to offer preconstrucion for clintz (via credits if need be). So whatever... some people will buy them, most won't and that's more or less fine, I'd say. I'd like to hear in a month or so, how well this actually went. I am somewhat weary about having a lot of those decks - that would lead to only rares having real worth as in its extreme, all other cards are guaranteed in these decks
