How it works
Declare Phantom Steed and Godo as attackers, triggering each of their second abilities.
Resolve the Godo trigger, untapping all creatures you control and causing you to get an additional combat phase after this one.
Resolve the Phantom Steed trigger, creating a token copy of Wormfang Drake.
When the token Wormfang Drake enters the battlefield, its first ability triggers, exiling Godo.
At the end of your combat phase, Phantom Steed triggers, causing you to sacrifice the Wormfang Drake token.
When the token Wormfang Drake leaves the battlefield, its second ability triggers, returning Godo from exile to the battlefield.
When Godo enters the battlefield, its first ability triggers, allowing you to search your library for an Equipment card and put it onto the battlefield.
