Well, that was an interesting read with a lot of good information. Great job there! I'd say this deserves to be stickied.
Of course, being the kind of person I am, I have some nitpicks and suggestions:
* On page 6, while talking about resource costs, stating that it's the cost of "deploying the card" is slightly misleading as Ability cards are played, rather than deployed. I know, extremely small detail, but still, calling it the cost of "deploying or playing the card" would probably be better.
* Multiple references to "Deployment cost" throughout the guide should probably be "Resource cost", as the term "Resource cost" is used in the tutorial and when hovering over it on a card, while I can find no references to the term "Deployment cost" in-game.
* On page 12, what you referred to as "hybrid purity" is called "dual purity" and what you referred to as "mercenary" is called "hybrid purity", according to the deckbuilder.
Any abilities or effects Characters in the Command Zone may have can be activated or triggered.
Unless stated otherwise, that is. Which should probably go without saying, but there's no harm in being abundantly clear.
* In a comprehensive guide, it might be interesting to note that it is possible to lose health or morale after
the game checks for losses, allowing a player to survive for a turn with 0 health or 0 morale. For example, when a Character dies to poison, the morale loss happens after the game checks for game losses.
* It may be worth noting that in the rare case that Charge and Vigilance are both present on the same card, the one stated last on the card appears to override the other one. It's a situation one probably won't encounter unless specifically trying to, but it's interesting none the less.
Haste allows Characters to be deployed to anywhere in the Deployed Zone.
As far as I know, when deployed from the hand, Characters with Haste can still only be deployed to Support (unless they also have Charge or Vigilance, in which case they're deployed to Assault or Defence). Not that this really matters, since they can instantly move to any of the other zones anyway.
When a player’s Character with Infect kills another Character through combat
Infect triggers on non-combat kills too.
Puffy, it even used to trigger on walrus and consecrating angel killing artifacts and locations, but that's since been fixed.
