Creature with Mobilize

All permanents on the battlefield (
Breath of Fury attached to another creature you control that does not have summoning sickness and cannot be blocked by an opponent and Creature with Mobilize without summoning sickness and cannot be blcoked and killed by an opponent).

Declare the creature with
Breath of Fury attached and the Creature with Mobilize as attackers, triggering the creature with mobilize, creating at least one 1/1 Warrior creature token that is tapped and attacking.
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 the Warrior token, then causing you to untap all creatures you control and to get an additional combat phase after this one.
Repeat each combat phase.

If you choose a Creature with Mobilize 2 or higher, this combo makes extra Warrior tokens each loop.
