x2Roaring Resolve
Once during your turn, you may put 2 damage counters on this Pokémon. If you do, search your deck for a Energy card and attach it to this Pokémon. Then, shuffle your deck.
Aura Sphere VolleyDiscard all Energy from this Pokémon. This attack does 60 more damage for each card you discarded in this way.
It controls waves known as auras, which are powerful enough to pulverize huge rocks. It uses these waves to take down its prey.
If I use Charizard's "Roaring Resolve" Ability with only 10hp left, does he get KO'd when I place the 2 damage counters before or after I search & attach 2 
Energy cards?
You must finish all the text of the Ability before checking for knockouts, so yes you would search your deck and attach Energy cards before KO'ing Charizard.
