Fractured Sanity
Sorcery
Each opponent mills fourteen cards.
Cycling 
When you cycle this card, each opponent mills four cards.
The body grows stronger under stress. The mind does not.

Rulings
Triggered abilities from cycling a card and the cycling ability itself aren't spells. Effects that interact with spells (such as that of Cancel) won't affect them.

Some cards with cycling have an ability that triggers when you cycle them, and some cards have an ability that triggers whenever you cycle any card. These triggered abilities resolve before you draw from the cycling ability.
