I think there's no arguement that this card is not very useful and does not fare well against other cards at the moment.
However, I don't necessarily think Nightmare itself needs to be buffed.
Instead, we should create a card or two that can make up a good combo with Nightmare.
Below are some examples/ideas:
- Change Malignant Cell card to a high cost card (like 10 poison elements). Malignant Cell is not a card that we can obtain/use, so I think it makes sense to do this. That way, when you Nightmare with Malignant Cell, your opponent is stuck with costly useless cards for a long time.
- Create a new card that activates its effect when it is sent into your opponent's hand. Something like, "Deck Eater" > As long as this card remains in hand, it removes one card from your deck each turn. I know this would be OP, so maybe we can make its cost 1 of any elements so that opponent can get rid of it right away. Another idea is something like "Parasite" > While this card is in hand, it takes away 2LP each turn.
Changes like these would make this game much more fun, I think.
