My understanding is that you will not get all the cards... there are specific core cards that you would get with the game and figures, then the other cards are sold in booster packs, much like MTG, with random cards in each pack. This is what the creator said on FB:
The firts edition of Legends of Signum includes about two hundred different cards. Among them about 80 caracters cards and they come with models in sets. Others cards, which called Support cards (spell, relic and tactics cards) you can find only in the boosters. Each booster includes 7 different cards of both fractions.
The Support Cards have an indicator of rarity:
- Common (green);
- Rare (blue);
- Legendary (yellow);
- Mythical (red).
In a booster you can find only Common, Rare and Legendary cards.
The Mythical (red) cards will be available as a gift for tournament or on the Kikstater.
Building and terrain cards are not included in the Battle deck. and you can buy them in special sets.
So, that in and of itself turned me off the game, since I don't think it will have enough local support to see people trading cards to get what they need, and it is just an added hassle to buy random cards. If I pledge for anything, its just for the miniatures
