This card can work well in a "Sylvan" Deck. Not only does it excavate, but it can help search for useful Trap Cards (like "Sylvan Blessing") that might otherwise be sent to the bottom of the Deck. In addition, this card can be used in the same manner as "Sylvan Hermitree" to re-order the Deck for more precise excavation.
In fact, excavating cards in general, like with "Kuribandit", "Archfiend's Oath" or another copy of this card, can help to trigger this card's effect.
In a "Last Turn" Deck, you can use "A Feather of the Phoenix" to place a Trap from your Graveyard on top of your Deck, which you can use to catch your opponent by surprise. If your Deck focuses on boosting your opponent's LP as well as fulfilling this card's LP cost, that Trap can be "Self-Destruct Button".
