i used to and still do play the original coc ccg/lcg whatever

is it worth me getting and starting again with the starter box? i believe all my old cards are still legal?

i know i would like new story cards, but would i be better just buying some ap boxes?

I understand that the current official ruling is that CCG cards which have been reprinted without change in the LCG may be legally played (with card sleeves), but be aware that some of the 'reprints' in the LCG Core Set have changed the text, icons or faction of their CCG predecessors. If you don't want those changed cards (and the cute little statues), then perhaps don't bother with the box.

Having too much money and too little sense, I got three of the box so that I can build competitive LCG-only decks rather than re-use my CCG cards (which are busy in their own decks, anyway).

cheers for the reply, is there a list of the now "banned/un usable cards anywhere?

right now , if you use the LCG format only , there is no ban restrict list(other than the 3 of limit in the original rules).
