Design a mission that you want to play, but not complete.
Currently all the missions (aside from kidnapped by demons) just have a beneficial goal on completion and don't do anything else, you put them down and until you complete the goal they're sitting there wasting space, your goal as the player is just to get rid of them.
But what if there were missions that were the opposite?
Ones with effects outside of completion, with more benefit to prevent them from completing, missions you actually want to keep on the field as long as you can.
You could make what is essentially an ability card that you can use multiple times, (pay X, do something, gain Y%) or a timed effect like tome (gain X% each turn) but I'd prefer if the completion method was a little more interactive and something you can try to avoid, though it depends on the effects.
The completion effect doesn't necessarily have to be bad, but you should still want to delay the missions completion as long as possible, if you want the completion effect could be nothing other than the card simply being destroyed and you losing its other effects, in which case you don't need to specify what happens on completion.
Also consider whether or not the card should be unique.
Deadline is the 16th of April.
--- Card Design Challenge Rules ---
1) The Judge appoints a challenge, it can be anything, making new card, redesigning an old one or whatever you wish.
2) All that wish to participate submit their card design. Each participant may only submit one entry per challenge, you may however edit your post as many times as you wish till the deadline.
3) After an announced deadline the Judge decides a winner. The winner then becomes the Judge for the next round, if the winner does not wish to host the next round a runner-up may do so instead.
4) All entries submitted before the deadline are guaranteed feedback, either in this thread or in another detailed feedback thread.
