Kraynox, the Deep Thane

Whenever a creature you don't control dies, return it to the battlefield under your control at the beginning of the next end step. That creature is an artifact in addition to its other types.
Whenever an artifact enters the battlefield under your control, put a +1/+1 counter on Kraynox, the Deep Thane.
