The main thing you are not taking into consideration here is this card:
This is your “everything I don’t have in my list” card. It’s your draw card. It’s your discover draw card. It’s your discover copies to draw my draw cards.
You don’t need draw cards when you have volume up + this which basically creates any draw you’ll ever need.
And depending on which deck you’re talking about, you also have Sivara. Between all of that, you shouldn’t have a problem with draw because your hand will constantly be filled with value.
