How it works
At the beginning of your combat phase, Helm of the Host triggers, creating a nonlegendary token copy of Godo with haste.
The token Godo enters the battlefield, causing you to search your library for an Equipment card and put it onto the battlefield.
Declare the token Godo as an attacker.
The token Godo triggers, untapping it and all Samurai you control and causing you to get an additional combat phase after this one.
