Choose Your "Build Order"

Your codex is a book of lots of cards.
Build your deck from your codex as you play.
("Build order" is the RTS game jargon for that.)
You start with just 10 cards in your deck and add 2 cards from your codex each turn.


Economy, Heroes, and Tech


Your tech buildings, heroes, and units can all be attacked in combat.
You can temporarily disable the opponent’s ability to cast certain spells
or play certain units by destroying their heroes and tech buildings.

Choose Three Heroes

The heroes you choose determine which cards will go in your codex.
No matter which heroes you choose, your codex will always have a coherent set of useful cards.
(Heroes sold separately in various Codex products, but the Deluxe version comes with all 20!)
