I mainly play with Ludia's Thievery ability and I can say that it's always a delight to play against war decks and the absolute worst against death.
Death god uses cards that deal damage to herself and are useless to steal.
"Out of its misery" FTW!
I do not play deception a lot and I am planning on getting into it slowly. So I thought understanding such stuff is important. And yes I agree with what you said and any tips are welcomed also!
