Finest Hour

Oracle Text

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.

Card Rulings

5/1/2009 Finest Hour’s second ability has an “intervening ‘if’ clause.” The ability won’t trigger at all unless it’s the first combat phase of the turn.
5/1/2009 Unlike other similar cards, Finest Hour doesn’t create a main phase in between the two combat phases. The second combat phase will begin immediately after the current one ends.
