Maybe it'll have to be that you can't just dump cards and buy stuff right away?
That would make me sadface. Like the real game you have to get out of that starting pit as soon as possible or you end up in loserville.
Having fixed starterdecks also build in inherent weakness. Whereas build your own deck mean you are to blame for fail not the cards you are stuck with.
You can buy/sell cards right after you start. Just like in the game itself, we just give players a pile of cards for starters, and let them do whatever they want with them. I think it's a better system than just giving them cash.
Btw.. you posted that fluctuating price spreadsheet a while back. Do you happen to have that somewhere?. I forgot where the link is. We could try it out in alpha.
I haven't done any in-depth analysis of those decks, but it looks pretty good to me. A couple of things though:
1. What was the "system" you used when building these? Was there a system, you did you just pick cards that felt right? I'm asking because I notices that some starter decks have 6 Dragons, while others only 4. If we make decks different this way, it might potentially lead to them being of different value.
2. I think that Underworld should start with only QT's, Dagger and a Shield. They have so many options to choose from, that giving them any cards, would basically be totally random, and might lead to a situation where everyone is playing the same rainbow deck. It would probably be best to make Underworld "special" so that they are the only team that buys most of their starting cards. It even fits the theme perfectly, because they are basically outcasts who start with nothing, while other teams get a starting army from their element or "King".
