Petrelli said:It says even if Uxie is knocked out, so yes, Memory Out counts, but the Uxie player can't use any powers after his turn begins.
Memory Out
Once during your opponent's turn, if Uxie is damaged by an opponent's attack (even if Uxie is Knocked Out), you may use this power. The Attacking Pokemon can't use that attack during your opponent's next turn.
Psychic Lock
During your opponent's next turn, your opponent can't use any Poke-Powers on his or her Pokemon.
