A lot of good games can be based on randomness. Being in control of the deck building means that your choices shape the odds. I used to have a similar viewpoint as you, but learned to really embrace randomness and the design challenges it presents.

I say this as a Magic player, where even the greatest players in the world can get screwed or flooded on mana. The possibility of screw/flood increases the importance of card draw/card selection, makes the playability of low-mana cards more important, and makes heavy color pip investment, multiple colors, and higher mana costs a very serious concern.
