This card has two separate automatic abilities that go off when it attacks. You choose which ability - destroy or bounce - goes first. Considering your scenario with Ruler of CHAOS, Geargod VII, the ideal situation would go something like this:

Attack with Hellheaven Dragon, Hellrend Heavens.

Destroy the size 3.

Resolve.

Bounce Geargod.

Resolve.

Normally Geargod would be able to save itself if simultaneous removal were to happen (like everything being bounced), but since this card has two separate auto abilities, using them like shown in the example effectively bypasses Geargod's ability.
