Well I could always allow it to be activated on Manasseh or magicians or evil kings of Judah or something. Defensive decks need all the art slots they can get. But honestly, I didn't do that because I thought that would make it OP.
The thing is, this won't be used by speed/offense heavy decks. That's fine with me. But a defensive deck that draws 6 cards a turn? That could make things interesting. I had to make the restriction last more than one turn, because in T1 games you experience turns where you can't make a rescue due to no LS available or other things; it would be a free D3 in that case.
Ok, how about this:
Identifier: May be activated on your evil king of Judah
"Draw 3. You are restricted from attacking or playing good Dominants for two turns. Cannot be negated."
