With Talonflame, it’s not as worth it since its only good STABs have recoil and you might as well use Rillaboom over Talonflame.
Just for comparison, the strongest priority in the game is Yveltal’s Sucker Punch.
252+ Atk Choice Band Dark Aura Yveltal Sucker Punch vs. 0 HP / 0 Def Celebi: 504-594 (147.8 - 174.1%) -- guaranteed OHKO
252+ SpA Choice Specs Typhlosion Eruption (150 BP) vs. 0 HP / 0 SpD Celebi: 714-840 (209.3 - 246.3%) -- guaranteed OHKO
252+ SpA Choice Specs Typhlosion Eruption (150 BP) vs. 0 HP / 0 SpD Celebi in Sun: 1070-1260 (313.7 - 369.5%) -- guaranteed OHKO
So yeah, it’s definitely worth adding support to this thing with Defog and Wish.
