Shadowverse: Rise of Bahamut

If you don't have a Dark Prince or something similar in your hand, it's not recommended to play this amulet; you can only do it if your opponent doesn't have any cards... Otherwise, it only helps them.

I know, but I was in the worst possible situation, so there were no alternatives. In the end, it did allow me to gain a slight local advantage, if you could see it, but by that time, the disadvantage was already too great.
