Combat Celebrant + Helm of the Host

Overview
Helm of the Host’s “At the beginning of combat on your turn” ability triggers at the beginning of each combat you have, creating a nonlegendary haste token copy of the equipped Combat Celebrant that enters that combat and can attack; that token can be exerted as it attacks just like the original, and each time a Combat Celebrant (original or token) is exerted when declared as an attacker it untaps your other creatures and creates an additional combat phase after the current one .
Step 1
At the beginning of combat on your turn Helm of the Host’s triggered ability triggers (it is an 'at the beginning of combat' trigger) and will go on the stack per normal triggered-ability rules .
Step 2
When that Helm trigger resolves it creates a token that's a copy of the equipped creature (Combat Celebrant) that isn't legendary and that token gains haste; the token enters the battlefield during the beginning of combat step and any enters-the-battlefield triggers it has will trigger at that time [2018-04-27].
Step 3
Proceed to the declare attackers step; you may declare the original Combat Celebrant, the token, and any other eligible creatures as attackers. Creatures declared as attackers must be untapped or have haste at the moment of declaration and are tapped as part of declaring attackers .
Step 4
As you declare Combat Celebrant (original and/or token) as attackers, you may choose to exert any that 'haven't been exerted this turn' — that choice is made 'as it attacks' per the card text, i.e., during declaration of attackers .
Step 5
When you exert a Combat Celebrant as it attacks, its text causes you to untap all other creatures you control and creates an additional combat phase 'after this phase'. The untap happens immediately as part of that exert action and untapping attacking creatures does not remove them from combat, so they remain attacking this combat .
Step 6
If you exert more than one Combat Celebrant (for example the original and the Helm-created token), each exert produces its untap effect and its 'after this phase there is an additional combat phase' effect; you will get multiple additional combat phases in succession after the current combat per the card text [2017-04-18].
Step 7
After the current combat finishes, the additional combat phase(s) created by exerting will occur. At the beginning of each of those additional combats, Helm’s 'at the beginning of combat' ability will trigger again if Helm is still attached and on the battlefield, producing another token for that combat .
Resolution
At the beginning of each combat on your turn Helm of the Host triggers and will create a token copy of the equipped Combat Celebrant that isn’t legendary and has haste; the token’s enters-the-battlefield abilities (if any) trigger when it enters [2018-04-27]. During that combat’s declare attackers step you may exert the original and/or the token as they attack; each exert untaps all other creatures you control and creates an additional combat phase after the current phase even if the exerted Celebrant doesn’t survive the combat [2017-04-18]. Helm will trigger again at the beginning of the additional combat(s) as they begin, producing another token each time if Helm is still attached and on the battlefield .
