Dueling Grounds and Finest Hour

[asmoranomardicodais]

Dueling Grounds says that no more than one creature may attack per turn, while Finest Hour gives you multiple attack phases. Does Dueling Grounds mean "No more than one creature may attack each turn (but the same one may attack multiple times)" or "No more than one creature may attack each turn (and the same 'one' creature that attacked the first time counts as a second creature for the second attack phase)". I can't seem to find info on this in rulings, and maybe I'm reading the card wrong, but what does the wording actually mean? Does Finest hour and dueling grounds work well together?

You really need to post the oracle text of each card whenever you are asking about relatively obscure cards like these.  However, I did look up the texts and here is what we have...

Finest Hour Oracle text

Exalted (Whenever a creature you control attacks alone, that creature gets +1/+1 until end of turn.)
Whenever a creature you control attacks alone, if it's the first combat phase of the turn, untap that creature. After this phase, there is an additional combat phase.

Dueling Grounds Oracle text

No more than one creature can attack each turn.
No more than one creature can block each turn.

These two cards should play together just fine.  The result will be that only one creature can attack, that creature will trigger Finest Hour, it will untap and can attack again.  Dueling Grounds does not mention any attacking restrictions, just the restriction on how many creatures can attack on any given turn.
