Have you ever intended to summon one mythic, but as soon as you go to touch it, blob pops up?

What if you could remove, sell, or trash mythic in order to make space?

I've had a couple games where this would have been handy when trying to get 7 iron kitty suits, and I ran out of spaces.

I think it would be fine as you don't gain anything except for a space if you got rid of a mythic. Maybe removing a mythic should cost 10 luck stones or something.

What do you think?
