Codex: Card-Time Strategy Starter Set

From Sirlin Games:

Codex is an RTS-themed customizable card game. You build your deck as you play from a pool of cards in your "codex" (though you won't actually need to use a physical codex card binder with this Starter Set). You'll grow your economy by hiring workers, and spend the gold on summoning heroes, leveling them up, casting their spells, and building more and more powerful units.

This Starter Set lets you try out the game with the Bashing and Finesse heroes. Once you go beyond the Starter Set, you'll get to play 3 heroes at a time and have access to a lot more cards during the course of a game. That said, the Starter Set helps you learn how the Codex system works with fewer cards that are simpler.
