Hello, i was thinking to a spell that is really powerful but that gives damage every turn it stays in hand without being played.
I'm not sure if it should be a creature, or a spell or a permanent!
I think it should be called something like "Inconceivable Idea", "Inexplicable Concept", "Perverse Thinking" or something like that.
The idea is something so powerful and mindbending that should be taken out of the mind, otherwise it will do brain damage.
Elements that could be fitting are:
- because of the high magic theme
- because it's something mindbending
- because it's double edged
The effect can be anything: direct damage, CC, PC, i don't know. I'm here because i need suggestions, after all!
But it has to be something powerful and really dangerous!
Another source of inspiration could be Lovecraftian concept of forbidden knowledge.
I hope someone like the idea!
