Cactus Game Design Message Boards

I was looking through some of my old card ideas, and while many of them necessitate an entire set to make them function properly (I like designing thematic sets more just as much as I like designing individual cards), at least one of them looks really cool. As it was originally designed, with only a minor change (presumably to go with the other "Foreign" cards:

Foreign Gods: Multicolored, TC enhancement:
Place on a hero: At any time, give your opponent an Idol artifact to convert that hero into a brown brigade evil character, then place this card on a hero.

Looking at it, I could easily modify it to work for Canaanites (they were most notable for causing the Israelites to go astray)
Canaanite Idolatry: Black, TC enhancement
If used by a Canaanite place on a hero: At any time, give your opponent an Idol artifact to covert that hero to a brown brigade evil character, then place this card on a hero.

You could even make a card that destroys Idols to convert evil characters back to heroes (taking from when, for example, King Hezekiah destroyed all the idols in the nation and brought Judah back to God.

Destroying the Idols of Israel: Purple, TC enhancement
Discard an idol artifact to convert a human evil character to a hero of any brigade.

I tried to incorporate giving your opponent a black Canaanite and that idol and activating the idol in their territory, but it ended up being really clunky...  Not sure if something like could be incorporated or not.

An artifact with an ability along the lines of "give your opponent this card and a black Canaanite to convert a hero to a brown brigade evil character."?

This way your opponent would be able to use it back on you as long as that opponent has a black Canaanite.
