Looks great so far. Thanks for designing!
On questlines - We don't need to tie it to the temple questline - there's a large number of distinct and unrelated questlines, and we will be expanding quests a great deal in the future. There's no penalty for failing a quest and they're able to be retried until completed, so there's no particular danger in people stumbling in to one that's too hard before they're ready. When quests get their rework, we'll likely add some indication of difficulty.
On story/text - In addition to decks and names, in order to put it in, we'll need the story. We'd certainly be happy with a very developed one, but it doesn't really need to be that complex. Most of what we have is just a few lines. What we specifically need for text for each battle is:
1. Mouseover/world map text - one line that shows up when you're picking which quest.
2. Battle start text - up to a screen full of story that shows before you fight each individual battle.
3. Battle won text - up to a screen full of story that shows when you win an individual battle.
Other stuff needed:
1. One-time rewards for winning every battle. These can be more or less what you want (I'll rebalance them if they're too low or too high). Currently, rewards can be gold, one or more specific cards, or the ability to choose one or more cards from a set of your choice. If you want something else (random cards for example, or whatever you can come up with), ask.
2. Stats (hp, mark power, draw power) for opponent. Also for player if applicable.
3. Special rules, if any.
4. If you care what region of potatotal island we stick it in, feel free to mention it. We will likely be killing off the whole "map" thing at some point (or completely reworking it), though, so feel free to ignore this part.
