I'm sure you would be able to do it, if anyone could. With 24 cards, could you design a deck that could kill within 17 draws, given that you know you're likely to be drawing every card in the deck? I bet it's possible.
The potential for a deck to too small aside, my point stands - the consistency at least will be improved and that's the point I was trying to make. As written it was even worse since it could then be applied to any deck to improve consistency, including everything up to 60 cards. Reducing the number of draws would make it potentially appropriate in some situations, and not in others - which is what we're looking for in card design, right?
