How it works
At the beginning of your combat phase, Halvar triggers, attaching Breath of Fury to the creature with haste.
Deal combat damage using the creature that has Breath of Fury attached.
Breath of Fury triggers, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to Ares, then causing you to untap all creatures you control and to get an additional combat phase after this one.
When the creature that had Breath of Fury attached dies, Ares and Deathrender trigger.
Resolve the Ares trigger, returning the creature from your graveyard to your hand.
Resolve the Deathrender trigger, putting the creature from your hand onto the battlefield and attaching Deathrender to it.
