Imagine a jutsu that takes up, say, 10% of your chakra.
 * You cast it, you're fine.
 * You make a shadowclone. Each clone casts it. each has 50% of your chakra and after it 40%. you're fine.
 * You make ten shadowclones. each has 10% your chakra. You cast it. You run out of chakra and die.

The problem is that using shadowclones makes it very easy to misjudge and cast a jutsu that's more than you can handle. The fatigue only comes at the end, too. So you could literally kill yourself by undoing Shadowclone Jutsu.
