I really wanted to make a monster that stood out from the rest. I think that by making it so that not only your opponent suffers, but you also suffer. It's a thing of Risk Vs. Reward, as you can use this card to punish people who constantly use Card effects, spells, and traps in order to acquire the cards they need to dominate you. If you find anything wrong with this card, please say so below, I'll try to respond.
