I'm sure this has been brought up tons of times. I found multiple mentions of it, but I'm going to bring it up again anyway. I really don't want to buy two more copies of the core set. That's just ludicrous. Isn't the whole point of the living card game that I won't have to break the bank like with a CCG? However, I still want flexibility in deck construction. If I make a shaper deck, of course I want three Toolboxes! Sure, I can only use one, but I can bring it back in the rare case it gets trashed. Also the odds of drawing it become much better.
Is it possible for FF to sell some sort of "core completion" set. All it would have to be is a box that includes 1x of all the 2x cards and 2x of all the 1x cards in the core set. By my rough estimate it would only be slightly more cards than what are usually included in a data pack. I would pay $25 for it. It might seem silly at that price, but it's still slightly cheaper than another core set, and way cheaper than TWO more core sets.
I think I'm going to start playing this game seriously, and I've already played with a few people who were crazy and bought three core sets. I would like to be on even footing without emptying my entire wallet.
