The original Arcomage game had an interesting effect that prevented a card from being discarded. This provides some interesting design space because it has both positive effects (keeping valuable cards) and negative effects (keeping trash cards). Renewal keyword is similar to this mechanic but is slightly different. I plan to add the new Renewal keyword in the Christmas update.
The keyword effect will be as follows:
"If card with this keyword get's discarded it will be returned to it's former position."
Important thing to note is that this doesn't prevent such card from being discarded. Player can choose to discard such card by using standard discard action or another card like
Militia. Cards that discard other cards and provide side effects like
Mediator will function normally. The discarded card will even show up in the discard pile, however after all that is done it will be returned to it's former position.
With this keyword implemented we are able to have cards that actually have strictly negative effects. Having this keyword on a rare card is very beneficial as it can't be discarded by other cards. Of course, we can have specific cards have the ability to discard even Renewal cards, also I'm thinking of giving this ability to the
Banish keyword as well.
Feel free to provide feedback on the new keyword effect and existing cards that should receive this keyword.
