Kyloria

Hitting an ally (or anything other than a hero) with Kyloria does not trigger its effect.

The triggered effect is not optional, if the hero you hit controls an item, you must gain control of an item.

If the hero that was hit controls an item at the time Kyloria hits, but does not when the triggered effect resolves, you do not gain control of an item and therefore draw a card.

When you gain control of an item, you retain control indefinitely until that item leaves the stack/arena or another player gains control of it from another effect.
