The problem with draw in this game is that it's only one use. The 3 use skills are exponentially more useful since you can use them multiple times. Hell, creation has 9 use which makes it the best excess mana dump in the game as it's essentially draw 1 for 15 mana.
Monotone is good because it lets you play out your entire hand without worry and usually gives you several draws ontop of that. Finally, duplication is good because you can dupe special cards for challenges.
