I love the general concept. I think its definitely something that should be considered. While I haven't gone through the numbers, so I won't opine on those, I will say that this is an obvious win.
I think the only 2 objections will be:
- what are the ratios to make sure the cards don't have unintended consequences (that's a negotiation imo, not really an objection).
- this will take up too much DEV time to make. I think it could be streamlined in a v1.0 rollout (like how the voucher shop started); and then in the future it could get way more cool.
I feel that this could appeal to 3 types of players too:
- the ones that like unique and interesting cards to play in a very niche spot (so definitely not OP but they should still have something to offer for regular gameplay - even if its infrequent the card would be played)
- land owners that want more production for their land game
- card collectors that like the opportunity to have unique collectables in their portfolio.
