Ruling Lucky Egg Jirachi

[Cypher]

If you have a Lucky Egg attached to Jirachi RR and Jirachi is knocked out, would you do first?

Serach your deck for a card (Power)

OR

Draw until you have 7 cards in your hand (Trainer)

The compendium answers this question specifically. Jirachi's Final Wish POWER resolves first. Also, take note of the errata to Lucky Egg's card text.

Final Wish (Jirachi - Rising Rivals)

Q. If my Jirachi has a "Lucky Egg" Pokemon Tool attached, what happens when it is knocked out from damage so that both the "Final Wish" Poke-POWER and the "Lucky Egg" tool are triggered?
A. Final Wish is resolved first. Effects that happen when the Pokemon "would be knocked out" are resolved before effects that happen when it "is knocked out". (Nov 19, 2009 PUI Rules Team)

Lucky Egg (Arceus)

* Three cards have been added to the list of errata for the Pokémon Trading Card Game. [...] The text below reflects what the card should say, not what was originally printed. "When the Pokémon this card is attached to is Knocked Out by damage from an opponent's attack and put into your discard pile, draw cards until you have 7 cards in your hand." If the Pokémon does not go to the discard pile (for example, if it goes to the Lost Zone, etc.), you do not get to draw the cards. (May 7, 2010 TPCi TCG Errata Update)
