Thanks Eldarain, the digital rulebook can be bought on the
webstore which includes a page of copy/printable tokens in the back. The general flame and blast templates are standard sizes, so that digital rulebook is really all you need to get started.
We sold a version that was just the cardboard and book in the kickstarter, but only 2 people ended up going for it, the rest putting in the extra cash for the full set simply because the card and rules are the most expensive part to produce in the boxed set, so doing it as a standalone pack does not represent much savings over the £60 packed box - the rules and card together would be at least £20, plus the expense of making a new, custom box for them, for the handful of orders that would choose that over the full set or digital rulebook.
Thanks!
