Those of you who have seen Elfen Lied will know of how tragic a character Lucy and her counterpart are, and so it seemed proper to give her a very powerful ability on her, but make it so that it was unpredictable as to when the bomb went off. Her low P/T also evokes how fragile she is.
Give her a go if you have the stomach for it!
Now THIS is a good custom card.
-I would say maybe one less colorless since she’s only a 2/2
-I would also change it to be a mana ability or an activated ability instead of paying when you enter the battlefield, even if that X cost can be used really nastily
Overall really solid though. First good custom card I’ve seen on here
