Do have any suggestions or advice in cutting down a deck from 63 or 70 cards to 50?
One thing my friend is doing with a lot of success is giving all of the kids different colors (or themes) for their decks. This works really well now but probably didn't in the past. For example, one kid could have Genesis/Romans, another Prophets/Egyptians, another Judges/Babylonians, etc. That way they can be competitive but don't have to play with similar cards.
