Worshiping the Lord would change the face of Redemption forever if printed. In a good way. However, to keep from being OP (and I think to be in accordance with what you meant), it needs to be worded thus:
"Negate and Discard a curse or, if played during your prep phase, enter battle phase and cause two Evil Characters to fight before attacking. Negate Enhancements played in side-battle."
This would be too long with it, so I droppped the CBN clause. Or, if you wanted it to do something in battle, too:
"If played during your prep phase, enter battle phase and cause two Evil Characters to fight before attacking. Negate Enhancements. Cannot be Negate if used by Jehoshaphat."
Love it!
