From the Omens of the Third Age release notes

This card is a hybrid card and can be included in your card-pool if your hero is a guardian or a warrior.
When A Bit off the Side resolves, it will generate a continuous effect that applies to axes you control for the remainder of the turn. That continuous effect gives axes under your control a triggered ability that triggers when that axe hits a hero. That hero must choose and discard a card when this triggered effect resolves.
