So to give a brief rundown, I'm making a card/dice game. You assign d6s to cards, those d6s are rolled whenever that card would roll dice, the d6s also determine a bunch of other stuff like that card's Initiative, their Power (when referenced by other cards) and basically everything.
Gameplay works by determining Initiative between all Ready cards (Ready meaning neither facedown or Exhausted[tapped]), and players rolling against one another in the result of a tie.
The card with Initiative can then either flip facedown or Engage a target (with an engagement causing the card to "exert" itself, which either costs a die from that card or causes the card to be Exhausted).
Combat is determined by the engager to make an Attack Roll, with the engaged to roll a Defense Roll, with ties resulting in the engager's favor. If the engaged card survives, they then make their own attack roll against an opposed defense roll as a counterattack.
Most cards have a positive or negative adjustment to their Attack or Defense Rolls, with the total bonuses equaling about +2 (for instance, a card may have +3 defense, -1 attack).
What I'm looking for are keywords that add some dynamics to the gameplay.
For instance, each facedown card has the keyword Protect, which says:
When a faceup card or player is targeted by an Engage, this card can Exert in order to become the new defender of that Engagement.
Another example I've considered is Ranged, which says:
While this card is not Exhausted, it always attacks first when engaged (unless the attacker has Ranged).
Do you have any other ideas? I'm looking for things that can be used for multiple things without being overly complicated or feeling 'unnatural', if that makes sense.
