Double-sleeving is a popular practice among players who have high value cards or want to keep their deck in top condition even after heavy use

Chrome Mox doesn't give any card draw or quality and it is hardly a utility card given that it basically only does one very specific thing

That ability uses generic mana, so you can use mana rocks like Sol Ring or Mana Crypt to activate it, making it easier to draw extra cards or ramp

And could get away with a worse Giant Growth in the case that the opponent didn't play enchantments at all

The biggest reason is just that you are spending mana to trade for cards from their hand
